If you’re into gw2 specifically, there seem to be 3 communities (two active and one basically dead I think) in the fediverse -

!guildwars2@kbin.social

!guildwars2@lemmy.wtf

!guildwars2@lemmy.ml

The only game I had for my Vita was Persona 4 Dancing All Night, but I played the shit out of that game. I miss it. No idea where my vita wound up.
