Crysis was notable for having a particularly amazing map editor included with it. When I say "map editor", it's actually an enormous understatement. The CryEngine 2 (and now 3) editors are game-designing software, with a ridiculous number of powerful tools that I can't even begin to list in a dinky little news post like this, so I won't. You know what I will say, though? It has built in motion capture software, for facial expressions when focusing on character faces for dialogue.
Yeah.
You can find the editor and a bunch of other neat stuff here, and the official documentation, which you WILL need, here. Now go make amazing things.
