Oh, Chiropteran, Dr. Boll think he's the greatest director to ever grace the Earth. He thinks that he is the only real genius and everyone in Hollywood are "retards."
MGS 4 is genius on a disc. It is the only game (as of now) I have for my PS3 and is the sole purpose I purchased the system. It was worth it. 10/10 in my book. A classic.
I think they're both great games, but CoD4 beats out CoD:WaW ever so slightly, in terms of story and multiplayer. Although I love both game's multiplayer modes, some of the things Treyarch added (such as vehicles) throw the balance off a little in versus modes. But then again, WaW does have co-op and Capture the flag, so those two things kind of balance the vehicles.
You're not alone Blinder. As much time as I put into multiplayer, it sometimes bugs me when that's all the dev focuses on. I think devs need to start putting an equel effort into singleplayer.
Just because it's not made by Infinity Ward and doesn't have a 5 at the end of the title means that the game sucks and is not part of the main series? Last I heard, WaW was the 5th game in the series, and IW is making number 6. And keep an open mind; Treyarch is perfectly capable of making good games. Don't bash the game without playing it just because IW didn't make it.
