I would have to say MGS4. that ending. Other than that, Burnout: Takedown. Absolutely mental game. Loved it from the first few seconds. Great fun with a steering wheel. Mercenafries. Had amazing fun blowing things up, and the factions system, and mafia shop really worked. The game that really introduced me to just messing about on a game, seeing what you could come up with. Monster Hunter. Good single player game, best online play of any game I've ever played. Working together to kill the huge monsters was great fun, also, a close community really helped the feel of it. It really brought me and my friends (playing online together) together, especially as at least 2 of them lived too far away to meet up with often. Best online experience I've ever had.
