There are plenty of game franchises that would be perfect for the LEGO treatment. Halo. Ratchet & Clank. Zelda. But God of War? Hrm.
Samir Karmieh's LEGO Kratos makes us wish the Danish toy giant would at least consider it, though. It could be one great ironic joke (much like most LEGO games are at the moment anyway), one of the bloodiest game series pared back for kids with a hero that's out for justice, not vengeance, and who beds down with not boobies, but a good book and some ice cream.
If you like, he's also done a few other gaming characters as LEGO, including Metal Gear's Solid Snake.
