And what would be your top recommendations?
I've been spending an unhealthy amount of time on recently added FIFA21 as well as UFC3 (something like 800 fights done now...). Also doing Outriders from time-to-time when I have co-op available - probably once or twice a week. Spent a lot of time surviving in The Long Dark. Enjoyed Fortnite oddly enough (that's free, not part of GamePass). I recommend Lonely Mountains: Downhill for some seriously chilled out, fun, challenging indie biking, as well as "Yes, Your Grace" if you have the patience for a choose-your-own type of story game (also quite good for when you just want to kick back and take it easy). On my to-play-when-I-can list are Desperados 3, Mass Effect Andromeda, Star Was: Jedi Night, Night Call (leaving soon) and a bunch of others.
The drawback is there is a lot of crap on Game Pass too, as well as many games that I just didnt connect with and uninstalled after 15 minutes of playing, like Cricket....
I also haven't bought a single game yet, however, I am keen to get a game or two soon that can test the console. Im sure Valhalla will be on a decent sale soon and considering Hot Wheels when it releases.
