the zero games
1) are already playable on most ds's, except the shitty overpriced ones
2) came out just the other day
3) have tried to refine the megaman formula by unnecessarily making it more complicated, and as such have actually made it worse, except maybe for the first game.
3.1) useless cyber elves, crap ranking system, repeated weapon animations, useless additional weapons, useless gimmicks - weather, stealing crap enemy weapons, cooking armor, cyber world etc etc
it's definitely a sign of something wrong with the ds library if this gets people excited
