Only BioWare games. And The Witcher 2. And Skyrim. I pre-order only the best stuff normally, the rest I wait for. Human Revolution is next to look forward to!
I regret and lament paying full price for Crysis 2 on Day 1, not worth half that. Had BioShock on Day 1, Alpha Protocol (no regrets) and a handful of MMOs I played from closed/open beta thru release (Age of Conan, Guild Wars, STO, couple of others, can't remember).
