I've had my DS for a good while now and my opinion is that while the games are good, some genres that you would expect to easily find on a portable are curiously missing. Fighting games for example; I seem to recall no shortage of decent fighting games on the GBA, particularly King of Fighters EX2 and some of those Gundam offshoot games. I really cannot find a substitute for these games on the DS, even though the ideas of wireless battling and WiFi matches would add so much more to their competitiveness and replay value. Am I missing something? Are there already decent fighting games on the DS? Any big fighting game titles in the making? Another kind of game that I haven't been able to find is the classic beat'em up. I know about Viewtiful Joe, but that game doesn't allow co-op play, and that's the biggest part of beat'em ups for me. Anyone know of such titles?
