Arcade is coming back, but not as part of the forums.
I intend to have a full REAL arcade, with proper licenses and stuff. I know Nintendo is not on board with any of this, so their stuff will be missing, but Capcom, Atari, and several others have dev kits last I check I can purchase once i can save up the money.
I also Intend to Partner up with rhe real life arcade down the street.
THAT is what I intend to do, failing that, we'll see what I cans care up, but it's a Damn low priority right now.
