Post a list of the stuff you want made and a playable demo. It doesn't have to be pretty or great, just something where people can walk around. How long have you been developing? Where did you get the current assets? Will the game be free or commercial? Is this standalone or a mod? Does it require some other game to function? What engine are you using?
The pipe in the first pic doesn't cast a shadow so either your real time shadows are poopy or your baked lighting hasn't been rebaked.
Well for now unity basic doesn't support realtime shadows and baking is poor. Unity pro should fix this, as it includes realtime shadows and so on.
Most of the models are made by me so far, I've used some royalty free assets as props and so on.
For my experience, I've worked with game engines for a good 5-6 years. And i moved to unity from bge about 2 years ago. I was looking for good engines with a good price - quality balance. I tried torque 3d and torque x. I even went for blitz3d and source plus UDK. But i finally got into unity because of it's user friendly interface and an excellent community which is ready to answer in any question/issue within 24hours.
As for the free to play/commercial stuff, I have already put alot of money in unity. But not specially in this project. I'd be ready to make this as a free to play, But if the quality reaches a certain level or it has potential for commercial value, i could maybe considering of turning this into a commercial product. A demo might be soon availiable if i manage to finish the first level in time. I'm very busy with my job these weeks so the the release of a demo might stretch a over a week or so.
This project has been around for a good month for now.
