Well it's the basic lets make a project and split profits if successfull.
As far as my role , well , a bit of everything , mainly going to focus on the environments , and will look for a modeler to help out with models and probably programmer . So in the end it should be a team of around 4 or 5 people at most , we will not be tackling the "Next-Gen" market because it's simply to ambitious , I'm going for Resident Evil 4 quality visuals (which i'm sure can be pulled off by gamestudio) and some great and gruesome gameplay. I do feel this project is possible to pull off , and considering the popularity of horror games should have a decent chance in the market , even withought all the normal mapping and the like.
