Rollercoaster tycoon classic
-RCT 1+2 in one
-Touch interface + port by original rct1+2 dev
-100 or so scenarios
-No added mxt or pay to skip anything, --gameplay is exactly like PC release
-Original soundtrack
I think the fact that RCT Classic is only worth getting on mobile because there are better options on PC doesn't help make the case that RCT Classic should be a shining example of 'mobile gaming'. RCT Classic is bit above the bare minimum for an acceptable rerelease of older games.
