Nope, there will always be a game or series that I want to play asap. I bought Witcher 3 and all xpacs at release. I bought the latest Pokemon games (Y and OR) at release, and most recently Doom.
Do I ever get regretful purchases? Sure, happens to everyone. They are becoming more and more rare for me though after years of experience. That and retail platforms like Steam are getting better with return policies.
