I've never done the 52 challenge & can't imagine I ever would. I tried for most of this year to beat just 2 games a month, and didn't like what it was doing to my playstyle- ignoring longer or tougher games in favor of short, easy experiences, choosing games to play based on 'beat-ability' over actual interest in the moment... it kinda sucked. I dropped that plan for the last quarter of the year- between PAX, Halloween, and holiday work hours, any serious free-time plans get torpedoed.
So no, I didn't rush through any games- but I largely avoided games that would require it.
While I still think I'll keep up play goals next year, if only to make sure I'm actually using the games I'm collecting, I think I'll change tactics from a pure numbers system. You know, like 'I want to beat RPGs neat year', or 'I want to play NES games', or something.
