If you like Bloodborne you should check out the rest of the Souls series. They stand undisputed as some of my favorite games of all time, especially Dark Souls 3. Besides that, I'd recommend Red Dead Redemption Online; It's pretty unique in the sense that it's basically an old-western themed GTA, I've been playing it recently on my free time and it's been a blast so far. I'd also check out Monster Hunter World if you haven't played any of the previous games and want to experience something new. The Fallout series is amazing but since you're playing 76 I'm sure you're already familiar with those
