Now this is something I figured would never happen in a million years, but Arc System Works announced they will be porting over Guilty Gear XX Accent Core Plus to arcades and will bring this version to Japan's AOU Amusement Expo this weekend.
You can play this game on PSP, PS2 and Wii but for whatever reason it was never ported to arcades. I'm no GG expert so correct me if I'm wrong, but apparently there were no major system changes in this version, but it did bring back both Kliff and Justice and introduced a new story mode.
It's not known if there will be any additional changes to the arcade version of the game but we will keep you posted. And hey, who knows, maybe it will show up at Southtown Arcade?
