Welcome back to VGC and congrats on your new system. :)
I'll add my voice to the sd card choir, and as far as which one to pick, I've had very good experiences with SanDisk Ultra.
As far as games go, what genres/types of experiences are you interested in?
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
