I had the most awesome dream of a video game idea. It was a lot like splinter cell only you had npc's that were actually smart. You had a dog npc that smelled enemies coming up, and would go off and get lost, and every once in a while you would run into the dog again and he'd have a grenade or something for you and a sort of robot dude that watched your back for you.

The whole game took place in an abandoned russian military base that was covered in snow. If you even stuck your head by a window there would be a sniper watching you and would take the shot. But there was no time limit and it wasnt like you were in a hurry to escape, or get a key or anything. Well, you did have to escape but to do so you had to cause a chain of events, but the big dramatic event at the end of the level was actually totally easy to walk right passed if you're not paying attention so you'd have to be really clever.

Very lonely, like shadow of the colossus, but at the same time there would be enemies to watch out for like in splinter cell or thief, but far less enemies than a traditional stealth game.
Man, the whole thing seemed so cool in my head. I even named it Spook.
