I played MGS4 as mainly a sneaking game on the higher difficulty levels. On the lower levels I blasted my way through everything...then again, I do that in any MGS game on the lower difficulty levels.

I will also wait to see what comes of this. I love the series but I would really enjoy a game more focused on a futuristic compound with all sorts of weird sneaking gadgets. It always takes place in the future but I always feel like I am playing with today's security mechanisms. We need hack of IR cameras and trout. Lets go!
