I pre-ordered three games this year (which as far as I know, were the only three games I ever preordered). Usually I wait a decent amount of time (6 months to a year) to see if any price drops/sales pop up.
Not that anyone cares, but these are what I bought this year. Pretty much the most amount of games I've ever purchase in a single year
MLB 13: The Show Metal Gear Rising Deadly Premonition: The Directors Cut Deus Ex: Human Revolution Max Payne 3 Hotline Miami Mission Impossible The World Is Not Enough Onimusha 1, 2 The Getaway Resident Evil 0 Ride to Hell: Retribution Hitman HD Trilogy
A combination of these. Usually I wait until I finish a game to get a new one but for the first time I've got a backlog due to numerous deals as well as day-1-purchase games that I have been interested in.
