Even if they are bad ones?
Just saying that:
a) this is a hobby project, no one is paying anyone, so people work purely on good will alone. Therefore, having an "iron grip" (if you pardon the expression) on the project might not be the best idea, as it might alianate people who actually make content for "your" (or should I say, "our"? ) game. Personally, I don't make stuff for this because of your wining personality (not that my personality is much better, mind you) and I bet no one is.
Still, it's not as bad as I make it sound - as some other projects I've had the misfrortune fr joining before realising just how little freedom anyone in them actually had. I don't think this project is going down, quite the contrary, I think it will be finished - altough not exactly as fast as it could be.
b) you said what you didn't liked about the model, I fixed it, and you haven't said anything after that.
c) you don't have a model for the starchaser. Not even a temporary one for testing. Makes no sense to not use something someone offers you for free, at least as a temporary fix.
