New Vegas melted 2 graphics cards for me. Play at your own risk.Speaking of backlog... I've had fallout 3 and fallout new vegas for years and never really bothered to play them (picked them up on some super cheap sale). I've heard new vegas in particular is great. Should I play that once I'm done with Subnautica below zero?
Seriously though, if you've got them, play them. There's no stupid base-building stuff in them and the story and vibe are good.
