3rd person views are working kind of strange. The camera should not go through objects behind you. If you back into something, it should zoom in the closer you get. As opposed to looking at the other side of the rock or other object, and not being able to see at all.
I usually play in first person view in games if they are rendered nicely. This one seems like it is, but the view seems 'off'. Like its magnified or something. Very hard to see. Needs a wider field of view.
Also, just curious if you guys have considered TrackIR support. Improved 1st person view and rendering + TrackIR would be very nice indeed.
