These last couple renders have been done using what's called a studio lighting setup, which is a real world photography technique designed for advertising, where the product is photographed with a couple of large, diffuse lights (meaning large and soft, not the texturing use of the word Diffuse) of slightly different temperatures in order to still allow it to have some shadowing and detail showing, as well as contouring, but also to minimize the amount of the product that's hidden in shadow. The only real major difference that you won't get in game is the soft shadows, but once in game it'll have normal maps and baked in AO (Which I include the normal maps in, making them a bit more realistic) so all in all it'll probably look better in game than these particular renders. Once I get it mapped and lit of course, a professional renderer will look better for sure, but you can take your pick, a model that looks pretty damn good in game and is playable, or a quad core processor spending 10-15 minutes chugging away at each frame (That's about 0.07 FPS =P)
