Although I'm not a heavy game player these days (some days don't have time to play anything), my tastes have evolved to line up more with the "hardcore" dude as far as enjoying shmups and actively seeking out "art" games.
Anyone who spends money on the more esoteric DC stuff is probably around that level as well. I keep buying DC shmups and spending sizeable money on "art" games like Rez. And of course, I actually play a lot of this stuff regularly as well (doesn't just go on the shelf).
