Yoooo Duderonomies and Babelonians, I made these posts in a Facebook video game group a while back and got TWO WHOLE RECOMMENDATIONS (Gradius ReBirth and "And Yet It Moves"). So read on and give any input you can, please.
PART I ZOWEE
With the Wii Shop Channel disappearing soon, I thought it would be good to bring attention to the WiiWare and Virtual Console gems on the service. Suggest any others you're particular toward, especially games that are only available digitally on the Wii.
- Zombie Panic in Wonderland (WiiWare)
If you're familiar with Wild Guns and other single scene, over-the-shoulder shooters like it, this is a great one with a fun, spooky theme, perfect for Halloween. It's been ported to other systems with added content (3DS and mobile), but I personally feel the original is best for the Wii Remote + Nunchuck controls; also, some levels were redesigned for the later versions, and I think they did them better the first time. The director of this game was also responsible for Little Red Riding Hood's Zombie BBQ, a similar game for the DS (and was also later released as a DSi title, probably still downloadable from the 3DS eShop).
- Castlevania: Rondo of Blood (VC/TG-16)
Still the only console re-release of one of the series' best. It plays similar to the older games but has a bigger emphasis on strategic combat and branching paths. Some of the best music in the series. Thankfully, this game is no longer the rarely played hidden gem it used to be, but there may be Castlevania or action platformer fans who still haven't played it, and the VC version is great (even if transplanting the new narration from the PSP version was kinda bogus).
- DoReMi Fantasy: Milon's DokiDoki Adventure (VC/SNES)
A fairly unknown cutesy platformer that was originally only released in Japan. It's a sequel to Milon's Secret Castle, but where that game was cryptic and kind of hard, DoReMi Fantasy is a more straight-forward game and one I'd relate to Kirby Super Star in terms of being kind of on the easy side but still a ton of fun. Rich graphics, unique ambient music at parts, and the only re-release this game has ever had.
- The Dynastic Hero (VC/TG-16)
Hudson's retooling of Wonder Boy in Monster World. The lead character design is a little lame, but it's got a CD soundtrack and is a little bit easier in parts than WBIMW, particularly the final boss who is a pain on the Genesis. If you enjoy exploration-based sidescrollers with RPG elements, this is a really fun one.
- Dragon's Curse (VC/TG-16)
Another Hudson retooling of a Monster World game, this being of Wonder Boy III: The Dragon's Trap. Better in ways than Dynastic Hero, you play as numerous animal forms that each have their own abilities. The level design sometimes makes little sense with no logic pertaining to how one area leads to the next, but it all adds to the fun and dreamlike world. I like the TurboGrafx soundtrack over the Sega Master System one.
- Monster World IV (VC/Genesis)
The last original Monster World game (except for the Dragon's Trap remake and the upcoming Monster Boy and the Cursed Kingdom), this one has a bit less exploration and open-ended design and is more straight forward, level-by-level. Some of the most amazing and colorful graphics on the system, it never got released outside Japan until this newly translated re-release. It's available on PS3 and 360 as well (and Xbox One through backward compatibility), but a worthy mention all the same.
- Castlevania: The Adventure ReBirth (WiiWare)
A really good game in the series, very loosely based on the original Game Boy game but is altogether a brand new game. M2 did a great job capturing what made the old school CV games so good (this is not a Metroidvania), with a really good FM Synth style soundtrack that plays like a greatest hits for the series. Using the "Load BGM" song from Akumajou Dracula X68000 as a stage theme is great.
- Contra ReBirth (WiiWare)
M2's take on Contra. It's a wholly unique entry to the series, mostly following in the footsteps of Contra III and Hard Corps. Great soundtrack here as well. If you like Contra or run-n-gun games, this is a must.
- Fast Racing League (WiiWare)
If you like Fast Racing Neo on the Wii U, or its enhanced port Fast RMX on the Switch, then you might be interested in this. It's the first game in the FAST series by Shin'en. It's slower than Neo/RMX, playing less like F-Zero GX but still a future racer. It has more an emphasis on collecting orbs to boost but also used to switch polarities, which in this game can mean changing from white to black in order to cling to a black strip of racetrack that's on the ceiling. It's a technical marvel for the original Wii system, and is a good bit of fun.
- Zombies Ate My Neighbors (VC/SNES)
To my knowledge, this has never been re-released elsewhere. I think just about everybody knows about this game, but it's a top-down run and gun with an excellent and campy B-movie horror theme.
- Super Mario Bros. 2: The Lost Levels (VC/NES)
It's on the Wii U VC as well, but NES games on the Wii U weren't emulated very well and tend to look and play poorly. The game is also part of Super Mario All-Stars, of course, but this is a digital release of the original Famicom version.
- Super Smash Bros. (VC/N64)
The originator, still never re-released elsewhere. Enhanced on the Wii due to it being higher resolution than on the N64.
- Chrono Trigger (VC/SNES)
As far as I know, the only re-release of the original version (putting aside the PSX and DS ports). An incredible RPG, even for folks like me who don't typically play RPGs.
- LIT (WiiWare)
A strange puzzle/action horror game from WayForward. The objective is to use light to get through several classrooms, as the darkness will consume you whole. Some of the later stages can get pretty maddening, really twisting your brain and using your quick reflex skills to get through a room.
- Muscle March (WiiWare)
It's fun, it's ridiculous, it's Namco's bizarre, homoerotic on-rails posing game! You use the Wii Remote and Nunchuk to perform various poses in order to fit through walls that someone in front has crashed through Wile E. Coyote style. The objective: chase down villains who have stolen your muscle milk.
- Alien Soldier (VC/Genesis)
A strange run-n-gun by Treasure and not one I'm totally sure I like, but I appreciate its weirdness. Packed with more minibosses than your typical Contra, this game never was released outside Japan originally and is a difficult one to get into. I hear once you get into the groove of the game it's a fantastic experience, but I still can't even beat the first stage.
Lastly, some others I haven't played yet but picked up because they sound fascinating:
- Jett Rocket (WiiWare)
- Vampire Crystals (WiiWare)
- Monster Lair (VC/TG-16) – a Wonder Boy shoot 'em up
- Beyond Oasis (VC/Genesis)
- Pulseman (VC/Genesis)
If you have other rarities, hidden gems, or overall great games that are on the Wii Shop Channel, recommend away! The ability to add currency ends sometime in March, and the servers shut down early 2019.
PART II ZOUNDS
Some more worth mentioning (I don't have much experience with most of these so I can't comment much):
- Blaster Master (NES)
A sidescroller exploration based game like the so-called Metroidvanias. I'm of the opinion the Switch/3DS remake by Inti Creates is better, but the original is really fun, although tough.
- Bio Miracle Bokutte Upa (NES)
A weird-ass platformer by Konami, never released outside Japan originally. It's a fun one if you wanna get away from the usual platforming classics and play something kooky.
- Super Adventure Island II (SNES)
Haven't played this yet, but unlike the nearly-always-running previous games, this one is more like a Metroidvania, or more specifically like Wonder Boy's off-shoot Monster World games, which is a strange twist of fate or intentional design choice, since Adventure Island had its start as a reskin of the original Wonder Boy.
- Faxanadu (NES)
An interesting exploration sidescroller similar to Simon's Quest. Super cool graphics.
- Space Harrier (Arcade)
I'm told this port is arcade-perfect. I had it on 3DS, but what drew me to the Wii version is its motion controls Nunchuk mode, where you move the Nunchuk around for fully accurate analog control, apparently simulating the freedom of movement of the original arcade flightstick. It feels better than an analog stick, which in turn is better than playing on a D-pad.
- StarTropics and Zoda's Revenge: StarTropics II (NES)
I haven't played these yet but they're some cool looking first-party Nintendo games, kind of unknown I'd say. Worth checking out gameplay videos to see if it's your thing.
- Ogre Battle 64
I heard it's great and rare, I dunno I'd probably suck at it. I know it's also on Wii U VC, but the visual quality of N64 games (and SNES, NES) on Wii U is pretty dark and muddy looking, so you'd be better off getting it for regular Wii.
- Cho Aniki (PC Engine CD-ROM)
Ridiculous, homoerotic, really great graphics and music. Kind of a novelty shmup, but it looks fun enough and is another import title.
- Cruis'n USA (N64)
This is kind of in the so-bad-it's-good territory, and I can't wait to play it during a game night with my buds. As a kid I played the arcade original all of one credit and don't remember having any impression of it other than the graphics being kinda neat. I was never big into arcade racing games, to be honest.
