So I went with Shock Troopers, Art of Fighting 2 and then 3.
Shock Troopers is amazing, heard so many positive things and was still amazed by it's quality.
Art of Fighting 2 oozes SNK Charm, music, giant sprites, the marmite graphics zoom. Looks fantastic, plays like the devil though. I would be fine with the jank controls if the A.I wasn't so brutal. I was warned but I didn't think it'd take nearly 30 min just to be the first character, think I can forget seeing Geese!.
Art of Fighting 3 Beautifully animated sprites, seems to control well. Didn't play much of it as I was heading off to the gym and still sore from the beating AoF 2 gave me.
Also picked up Fatal Fury: Battle Archives Vol 2. Fantastic selection of games and even the "Duffer" being Real Bout 1 shows the quality, bar the Ring Out element the game is still quality and holds up well. Did have an issue with P-Moves with Terry though.
