My motivation comes from the time and effort I spent for developing the characters, this is applicable for QC. There were other projects i planned, but I gave up on all of them. My goal is not to make a game that everyone likes, it is making a game to express my thoughts and fantasies to myself in a more-than-satisfying way, and I want it nothing less than awesome. I'm lazy and I always drag things, so there aren't many things I've done. But those things I've done are at their best, and this game of all things should not be an exception.
There you go, I already got carried away and am breathing hard right now, lol!
EDIT: And yes, the delay doesn't bother me, cause that's just me. I always take my dear time, but I believe I'm going to make this game in the end. If not in RXP, maybe in another engine. But QC WILL see light someday.
