BAAAAP! Time's up for the nominations! Not like you needed that many. Voting has begun, and we're back to a poll! 9 games enter, only 2 will make it to the final vote!
However, one rule: Two games from the same series cannot enter the final vote together. If, for example, Portal 1 and Portal 2 are first and second place, the game on third place will have to rob Portal 2 of its place.
An 'obvious patch rule': Black Mesa and Half-Life 1 cannot be together in the final vote either. I don't suppose this needs explaining.
