Proper Belief Systems
While I was writing this, I had an Earthworm Jim episode stuck in my head. Each world is contained within a snow globe, and all the snow globes sit on a shelf in an outside universe (and, presumably, that outside world is, itself, contained in a larger snow globe).

When the question was asked, that's all I could think of.

I've got to say that I enjoyed The Thirteenth Floor. Simulations built into simulations made for an interesting concept and I liked the subtlety of each simulation has less color than the last.

Ooooh, good catch. I hadn't noticed the color motif before. Well spotted!
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
