The only games I used to play on the old arcade was spleef, Hour Glass and TNT run. I'd like for all the games to be "Remastered" And given their own playlist. If they make the "Retro" games standalone, the community which plays arcade will be split, so I'd prefer it to be a Retro Arcade Playlist, instead of tons of gamemodes.
The Remaster could remove bugs. I'd however like to keep the original maps.
