There's not really one special title that comes to mind when thinking of the rest. Probably as I didn't play the major hitters like GTA on PS2 etc. I don't associate them with one game.
Yeah the Switch is like this for me.
I played Breath of the Wild on Wii U, so while I enjoyed a great many games on Switch, there is no one game that jumps out as emblematic of the console in my mind.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023. (And over 130 million lifetime)
