My two favorite ones are the Fallout one and the Adventure Time one but both are kinda outdated I think. I really like how creative they are~
Like the Adventure Time one is really flat and follows the show's style very closely which is neato, I really digged the armor which was basically samurai armor, but the Fallout one really changes things up with the sky being as dank as it is in the game, and making like everything all muddled and gross. I loved how they handled things such as making the emeralds bottle caps.
Also dig the ones that are normally in videos, like the one that is used for like every tekkit video. I'm not a fan of switching the shovel the other way to make it look more like you're digging, for some reason it just looks weird paired up with the other tools.
