This is a thread where you can detail your opinion for the absolute best game ever. It is like a poll, but with infintessimal options, I will simply come and post whatever the poll stands.

Rules

1. Must give a real game.
2. Must be a game you have played.
3. Must give reason why you think it is so awesome.
4. You only get to say one game. You only post once.
5. Do NOT count the votes yourselves. That job is intitled to me.
