Yeah so? A lot of games from PS4 are on PS5 and work wonderfully. You probably didn't see what a shitshow was the transition from PS2 to PS3, since the hardware was so different they couldn't just port the old games onto the new system. What they are doing right now is beautiful, same for Xbox, where I love how connected to the PC it is now.
Both Sony and Microsoft are finally doing what was asked of them before. Now if only Nintendo weren't such bozos and greedy....
People want to play classic games on newer consoles, that is why the demand for a GTA collection was high (and Rockstar not doing it themselves was a shot in the leg for them). With Elden Ring, Horizon 2, God of War 2 and more coming in the next half a year, you know it's gonna be a good time to be a console gamer.
Just don't buy stuff day one without watching a review or two first. I don't trust my mother to make a good cup of coffee and I don't even trust CDPR with games anymore. ALWAYS. CHECK. A. REVIEW. FIRST.
