Who's complaining? I'm just answering your question. Descent is not as popular as Sonic or Zelda. More people have played those games than they have Descent. That's just a fact. I'm sure it still has a decent following. A lot of old games still do.
I don't get why you're getting defensive. It's not like I'm talking crap about Descent or anything. I'm just giving you a reason why it's not remixed as much here on OCR. We encourage remixes from every platform, but in case you haven't noticed, most of the music here is console-centric, because more people played games on consoles when they were kids than they did on PCs. It's just a result of people's nostalgia.
And to be perfectly honest, I really dislike when someone posts a "Why aren't there remixes from <GAME>?!" thread. Can't you people just read the guidelines and post a normal request instead of turning your request into an indignant complaint about artists' song selection? How hard is it to just title your thread "Descent ReMixes Please?"
People will remix what they want to remix. If they want to remix Descent, then more power to them. The game had a good soundtrack. But seriously, we can do without the feigned bewilderment.
