I decided to play a bit of Borderlands 2 and see the quests I never did back in the day. I also stumbled into the Minecraft Easter egg, which was kind of neat.
I was playing as the Mechromancer. Her bullets bounce off surfaces to hit targets, and she has a pet that flies around to kill things. If you ever want to get in the worst possible FPS habits, play a character who negligently runs around and fires shotgun blasts in the general direction of enemies. And it works. It seems like that should not receive positive reinforcement.
