This question popped up again briefly during this week's Bombcast. As great as MGS was, the sheer audacity of Kojima flipping off gamers and fans with MGS2 made me love it instantly. It's one of the select few games I've beaten twice-in-a-row in a single sitting. 3 was a fantastic game as well, but the up-its-own-ass insanity of 4 tickled my MGS bone in all the right ways. With Ground Zeroes and Phantom Pain on the (distant) horizon, hopefully there will be one of each type of Metal Gear for us to enjoy, but I'm worried they blew all the crazy and it's all self-serious from here on out.
So where do you fall?
