Well, rayman legends & sonic mania have been out for a while. Haven't played the latter but just played through rayman for the 1st time and imo is a better game than DKTF in every category - was blown away!
Unless you meant first Nintendo exclusive great 2d platformer?
yup that's what i meant. sonic mania and rayman can played on any other console or PC, heck rayman is even on lastgen consoles.
