I think, summer older games which are capable of running with either smooth 45 / 90hz or better and HDR compatible. For example Hellblade - Senuas Sacrifice looks absolutely stunning in HDR on the OLED. The LCD looks rather flat and lifeless.

Germany, got mine today. Bought roughly 3 hours after it was available. Been lucky, I guess.

I got the 256 gb version 4 month ago. Thinking it would be ok and I just extend it with SD cards. But in reality these are expensive too and much slower in terms of loading times etc. So I swapped the internal SSD with a 2tb SSD and finally I don’t need to uninstall and move around games every week. So I strongly recommend going for 512 gb (OLED), or buy the 256 and swap the SSD.

Yes. But sometimes you can find a micron 2 TB SSD for like 140 - 150 $ so this would be my choice (actually it was my choice few month ago and I’m really happy with it).
