No I don't mean boss fights that make the game crash, I mean boss fights that kill any enthusiasm you might have had to keep playing. For example, I gave up on Borderlands 2 because of this fucking *****:
Angel. JESUS. This encounter still sticks out in my mind as the most tedious boss fight I have ever had the displeasure of taking part in. This is because you don't actually fight her you just do a really fucking boring horde fight and it's in no fucking hurry to resolve itself. It also sticks out because I was with some other players during the fight and we ran out of potential conversation it took so long! Oh it was fine for a while, running around, shooting robots, and reviving each other but as the fight dragged on and the conversation dried up, I realized I was on autopilot. Just doing with zero understanding while watching the other players get as tired of this bollocks as I was. Oh we managed to get through it but I never picked up a Borderlands game again. So well done Angel, you killed Borderlands for me.
So that's mine, what about you guys?
