Is this the first time you get a DS (to the Original Poster):
'cuz I love MegaManZX and ZX Advent, as well as the Phoenix Wright games.
Nanostray and Nanostray 2 (part 2 more so) are decent shmups for the system.
Final Fantasy Tactics A2 is pretty good so far (I've had it and have been playing it nonstop since a few weeks ago when it came out).
Advance Wars: Dual Strike and Advance Wars: Day of Ruin are good too.
Hotel Dusk: Room 213 and Trace Memory are good point-n-click adventure/story games.
There's so many other games for that system that are good, just can't think of 'em off the top of my head right now.
As I've said before, the DS is the new SNES.
I had my DS ever since it came out. I have the DS castlevanias, the DS megamans (starforce included, never played BN. Actually, I didn't really like SF, since it's more damn repeative than my final fantasy 3 DS), mario kart, New super mario, YGO nightmare troubador (this one was just plain figgin' boring), Lunar Knights, pokemon diamond version, and uh . . . nintendogs. Nintendogs is actually my sister's though.
FFIIIDS was also a damn long game, it isn't even funny. Too me 70 hours to beat it. Not including the 80+ hours that I died and had to back track like forever since I never really saved much. I also hated the fact you HAD to level up to beat some bosses. (Last boss is a big one). It was very fun when I was playing it, but when I look back, it should of been fustrating, but instead turned into one of my best lasting games. It's more of a paradox.
The ones I heard interesting is contra 4 and prime pinball. Not sure why pinball, but if contra 4 has two previous contra games in it, that might be a reason to get it. Three games in one, score. I also don't need to get the others, since it's in the same cart. Double score.
Is prime hunters any good? I loved the 2D side scroller of both the GBA ones, but I despise 3D first person games for reasons unknown. Don't know why, I just hate them.
So can cantra 4 have the those other games in it playable before the actual game, or they unlockables? I never played contra before.
