Indeed, I usually don't post straight away so as not to influence other's answers. XD
Witcher 2 on 360 and Crysis 1 on PS3/360 seriously impressed me, as games designed to push high end PCs of 2007/2011 squeezed onto 2005 console hardware.
The ports of Doom 3 and Half-Life 2 to the original Xbox were similarly remarkable.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
