Despite the shit writing, probably Borderlands 3 if we're talking about time spent vs money spent. Trying to think of any other game this year, and I'm drawing a blank. Maybe Devil May Cry 5, REmake 2, Sekiro and Bloodstained, but that's about it (they were all worth the money, but none of them got the same playtime as Borderlands 3). Mostly been playing games from the previous years. The only game that I've purchased so far that felt like a waste of money though would be Indivisible.
Unless it turns out to be really bad, I think the next game I'll sink a ton of hours into would be The Outer Worlds.
