I'm a huge fan of heroscape. One of my biggest dreams, in fact, would be to create a Heroscape video game. If you have never played it, it' basically a clash between heroes from all genres in space and time brought together in a massive battle. You can make a team of romans, and aliens, and fight against a team of elves and mechs. Truly an epic game.
