Kind of... none. My backlog is huge and new games that interest me enough for me to get them even the year they're released are extremely rare, so I usually play games even older than last year's. Due to my tendency to get games so late anyway, I don't get hyped all that much, so if anything, I'm pleasantly surprised when I get to a new game (well, new to me). As a result, I don't recall a single time I thought "wow, why didn't I play this earlier".
