i got kind of into smite recently, and it was fun, but it felt like i was playing it because i was telling myself "you should learn a multiplayer game! play smite!" and having fun just because i was invested in the current game. i never really WANTED to play it, i just felt like i should. what kind of online/multiplayer games are you into right now?
I've kept going back to Warframe for a decade now, so I'd generally recommend trying it. All the bits people actually play are PVE, and the community's generally pretty helpful. It does require heavy use of the wiki late game though.
