Bought into one of these just this year on a whim, despite not being into fighting games much. Unfortunately it's tough finding games for in my area. That said, almost everything I've played on it has been quality:
- King of Fighters R-2 is a really solid fighter with team- and solo modes. Lots of characters.
- Samurai Shodown! 2 is the best game I have for this system. Amazing game and really opened my eyes to why fighting games are cool.
- Fatal Fury First Contact is the least interesting fighter of these three I've played. Solid, but less characters, no team mode, grating music
- Neo Turf Masters Pocket is a superb handheld golf game. Compares very favourably to its competitors on WonderSwan/Game Boy.
Right now I'm playing Card Fighters Clash, but to be honest I'm not feeling the hype yet. I'm not really sure what the point is yet, do I just need to beat everyone I find? Collect everything? The translation is super wonky on this one too, some cards flatout do the exact opposite of what the text says.
Hoping to wind up liking this one more as I get further into the game, because I enjoyed games like Pokémon TCG on GBC or YuGiOh on PS1 back in the day. Really expected to click with CFC faster, sadly. The core card battles are good fun, at least.
