I'm a pretty good 3d artist, so it's very easy to find people who want to work with me on game projects. Sadly, I've yet to meet one who actually kept the enthusiasm the whole way through - even when I've literally made all the art!
It's literally maddening to see so many games made with programmer art - and I just can't find anybody reliable to work with on any project. And, before you ask, I've tried contacting the makers of programmer art games - and it's almost always the case that they've moved on or got a job.
I just want to work on a project where I can see stuff through to the end without relocating to get a job at a studio. But if I post an ad, I just get a ton of replies from people who will drop the project after I've invested hours of work into it - no matter what I do.
