Is it the only game to ever come out on 3 generations of Nintendo hardware at the same time? (Switch release pending) Last Wii game, twilight Wii U release, Switch launch title. Definitely not my kind of game, but it's notable. There has never really been a proper window of time between generations of Nintendo hardware to warrant something like this.
Exact ! And pretty interesting thing ! Never seen a such game on three different generation for any other manufacturer. It just sadly reminds us how the Wii U life was pretty short....
The only other situation I can think of is FIFA 14 being simultaneously released for PS2, PS3, and PS4.
I honestly can't remember any others besides FIFA. I don't even think PES 2014 came out on the PS2 (I think PES 2013 was the last US PS2 release, FIFA 14 came out in Mexico and Europe, but I've never seen a US copy of it). It looks like I have to get a Just Dance game now.
