As Noble said, Gamepass! It has tons of MS exlcusives you've missed on xbox one (and possibly 360). For games not on GP, Yakuza Like a dragon is a cool JPRG if you like those games. Speakin of JRPGs Gamepass has a slew you missed out on if you only had Nintendo consoles. Might help to hear what kind of genres you like to further assist.
I have a wide range of tastes
Platformers, action and adventure, strategy, RPGs
Also question about gamepass do the game download onto the console and how long do I have to play them?
