Atari was the original publisher of Roller Coaster Tycoon 3, and the hideous undead shambling thing wearing its skin seems to still have the rights to the series. I don't see Atari's name on anything to do with this version of RCT3 so it looks clean enough, but can it be verified that 2015-Atari doesn't have anything to do with this version of the game?
Still bitter about TxK? You bet!
