(my wife and I are both 31) I sometimes feel the same way that maybe I'm too old for it but then my preschool teacher wife keeps reminding me that you're only as old as you let yourself feel so we have a fun time gaming together and I still game by myself on games I like. The wife and I play D&D and we larp and all kinds of things a lot of people our age thinks is for kids. We have a blast and we hope our daughter has just as much fun as we do when she starts growing up.
