Borderlands is useless if you play alone. Didn't even finish the first title, totally skipped the second. I do like the art style, just not a fan of the gameplay itself.
For a game that started way more serious, I am kind of curious what it could be if the rendering was more realistic and the fun being toned down, but it seems Rage 2 will provide plenty.
Not touching anything Gearbox themselves make anymore though.
