^I pretty much agree with that entire post. Except that I did love Act 4 of MGS4 the most. It had some nice stealth aspect to it, including the fight with Crying Wolf, and it's less practical to go through the Act guns blazing because the robots will rip you apart. I find it to be the most stealth oriented part of the game. Whereas the rest of the game doesn't benefit as much from stealth, which I dislike.
