See thats just your opinion. I think Castlevania is in a delicate state and is taking a chance at something that will help it survive.
Yes, it is an opinion, and yes Castlevania needed to try something different; however, I don't agree with the direction I've seen and played up to this point with LoS. (And in a recent thread here, many agree). For every element I like in LoS (using the whip as a multitasking tool and the graphics, for instance), there is a gameplay, level design, story, or art direction choice that causes it to come crashing down for me. The very fact that it's combo-intensive, isolates its platforming, and relies entirely on fixed camera angles drives me up the wall. The whole "feel" of Gabriel's whipping and jumping mechanics would have to be overhauled to give us the kind of action-platforming level design that is at the heart of the franchise. (IMO, to do a 3D CV game, you had to start with the "64" games as a baseline, and build from there. But few designers want to give players that kind of control in their game's level designs). That said, it may be possible to make a more solid game that LoS with LoS' setup; however, I don't see it blowing me away. For as good as a template along the lines of DMC or GoW can be, it's never quite as open, dangerous, or varied as something like we saw in the Maximo series by Capcom, which is also reflected in CV64, especially in stages like Level 2--ascending a dusty, torch-lit tower while dealing with crumbling stairs, flipping/moving platforms with spikes, medusa heads, bone pillar projectiles, bats, and falling guillotines: that's about as Castlevania as you get. And you can only do that because the level is a full 3D space, not fixed, carved-out renders, and the character has full control over jumping and whipping without the hindrance of things like combos. And that makes the sub-weapons come in handy against ranged enemies guarding obstacles.
How so?
With regard to Metal Gear, first they threw aside Solid Snake and the hi-tech world and decided Naked Snake and the Cold War era was more important. Then they brought back Solid Snake as an old man and sloppily closed off his complex story in a sloppy game. Then they've been fussing around with HD collections of some MGS games they've already released in SD box-sets that went out along with MGS4, and added in Peace Walker--a game that was not too long ago released on PSP as an exclusive. Now, they plan to follow that up with ANOTHER HD collection for PS Vita. Finally, they announced Metal Gear Solid Rising: Lightning Bolt Action, supposed to be a mixture of strategic swordplay and stealth accounting for Raiden's transformation between MGS2 and MGS4, which has now been degraded and handed off to Platinum Games, renamed Metal Gear Rising, and turned into a Bayonetta-style action game that takes place after MGS4. The whole brand has been watered down. Oh, and they're talking about doing a game about The Boss from MGS3 next and her Cobra Unit during WWII. That is so insignificant at this point and further distorts the focus of Metal Gear. The only reason they'd do that is because they know they could do something dramatically different with a different premise...but that's almost like giving up on a franchise and making a new one, IMO.
But I digress on both of these points. I am being too negative, and I apologize for that, but these franchises--like Mega Man--kind of define gaming for me, and I don't see them living up to their names (or being allowed to) and I don't see new franchises really replacing them, either.
