Haven't been playing for a long time because I haven't set up the xbox in a long while, but Borderlands 1. Have been playing that game on and off more than a decade now. I don't think the base game (playthrough 1 only) on its own is 1000+ hours long, could be wrong, but it's long enough, especially with the DLCs. I think I've beaten playthrough 1 and 2 with 2-3 of the characters and have yet to beat all the quests with any of them because of a certain DLC boss fight quest.
It's a game I absolutely fell in love with. Started with the 2nd game, which my brother got, but I later got the 1st because I wanted to see how it was compared to 2 and I'm a bigger fan of the 1st game. Played the pre-sequel, it's fun but not as good as 1 in my opinion, and have no experience at all with 3.
Imagine being the bootlickers who wrote that malicious code. Rest in piss, all of y'all.
