As a 29 yo female I thought I had grown out of them for a few years in my mid-20s when I just couldn't get into any game, then Assassins Creed 2 came along and for some reason I just couldn't stop playing. It was different to anything I had played previously. I had that excitement back.
I think a couple of things happened. Firstly I had a lot of other stuff going on which distracted me or seemed way more important. Secondly, although I reckon I've always been pretty discerning about the quality of games, my tastes changed as I got older, where the games that had been fun before were not as fun, too simple, immature, or whatever (to me) and the games that had seemed less interesting but were also critiqued well became more interesting (again to me) eg. from the age of 13 I loved and only really played FPS and RTS games. All on the PC. Now I mostly play action RPGs and 3rd person shooters on consoles, and most importantly, ones with good storylines.
My suggestion: Read a few reviews from sites you trust and pick a number of well-reviewed games from different genres. If you liked FPS or sports before, try RTS or action/adventure. Mix it up until you find something(s) you like, and then go from there.
