Newt's right. Part of it, in my opinion, is I generally can't find stuff that I actually want to play. I don't feel like playing yet another fps or stale badly written boring battle system grind fest rpg (not to diss all RPGs, some are fantastic and the best ones make it my favorite genre, but some of them.. Eh). I want innovation. Personality. A game that was clearly cared about by its dev team. Games that have one of those traits aren't all that hard to find, but games that encompass all those things are hard to come by. A lot of the games I've tried these days feel like they were sort of put out on the assumption that because there's a game there, people will play them (maybe the problem is all the iOS stuff that's been disappointing me lately... But what can you expect when devs are forced to charge so little, I guess. :P). Maybe I've been missing a lot of the good stuff, but game development is just so much more enjoyable to me, I'd much rather spend my time working on my games and make what I want to play instead.
It helps that c2 is so fun to use. :)
Edit: parts of my post sound a little too much like a diss, which isn't what I mean (edited it a bit). There are tons of very talented people working on games that don't interest me (not to mention how hard it is to make a game turn out how you really wanted it), and I also don't look down on the people who do like them at all for enjoying them, different tastes and such. I just find developing games to be much more creative, interesting and enjoyable than playing them.
I also don't think it's necessarily a transitional thing. I've always been fascinated by making games, the difference is I wasn't able to make them before - though I did try, making sprites and such for the games I wanted to make. It's easier than it's ever been to make games, and that's a pretty recent thing.
