We talked about it last week, but it’d seem that SNK’s The Rhythm of Fighters (Free) hit the App Store early this morning. Basically, it’s King of Fighters ($0.99) except instead of button mashing you’re pulling off rhythmic combos in time with the music:

I’ve spent a little time with it, and it seems like a neat idea. It’s got a bunch of tracks included which should be recognizable if you’re in to SNK games, and additional bundles of tracks that can be bought for $1.99 IAP’s each.
