At this rate, sure as fuck nothing made from Atari.
RCT 2's core game was great, but expansion packs were God awful. Adding nothing but shitty looking theming to the game that you couldn't even mix due to the arbitrary limits made worse because the sloth coaster is apparently so distinct from the swinging coaster.
RCT 3 I find suffers the inverse issue since core game is pretty boring until you can make water parks and aquariums.
