Sometimes the simplicity of a villain is what makes him good, I like the way vex acts and does stuff, you get from the start that Hey! He’s the bad guy, you were only lucky to escape him the first time. Tho if I am honest I wish they would have a more variated boss fights (at least with Vex)
I can't tell what some of these bosses depict from the series, but I know a few: Little Big Planet 3- 34:04 - Vexterminater (Titan 3) 31:44 - The Giant Befuddler (Titan 2) 23:18 - Vexed N.A.O.M.I ([Almost like] Nana Puds Gaurdian) Little Big Planet Karting- 7:04 - Vexed Mamapede (Centipede/Snake/Caterpillar/Dragon[Can't figure out which] Boss)
Can't be any less interesting than the way Paper Mario has been these past few entries, both PM and LBP are similar in concept but at least this series is taking a creative approach with this game.
