This is the place to make suggestions about what kinds of things we can model. This is a brainstorming thread. No idea is a bad idea. Keep in mind we haven't decided on whether we want to be very specific ("An Xbox One controller") very generic ("a mythical creature") or somewhere in the middle. All ideas are welcome right now.
I'm going to go a step further and say maybe we should first decide on Organic (creatures, characters) or Inorganic (guns, knifes) modelling. Since this is the first round Inorganic would probably be the way to go. Most inorganic can be done using low-polygon techniques whereas organic tends to get into NURBS and a higher poly count to give better definition of the curves and surfaces. So, Organic would undoubtedly take a higher time commitment. I think that would stand true even though we are all at different levels.
