Our latest trip down the internet's (You) Tubes leaves us basking in the mash-up glory of JudgeSpear. This videomaker's page showcases dozens of game crossovers, with characters from different titles fighting, and even non-gaming characters get inserted into the action.

If you're still not convinced, let this sway you: Mike Tyson makes an appearance near the end. Watch the video after the break.
