What was the first game you've ever been excited for/interested in, but decided to wait for it to go on sale?

As it says on the tin, first game that hooked you, but not enough to buy Day one. For me, It has to be DOOM: The Dark Ages. I thought I'd be interested, but I feel Eternal satisfied me enough to not want to buy at launch, though the 120 AUD price tag for just a standard edition pre-order certainly helped lol
