Hi, I recently played the tech demo and I was very impressed with what was offered. My suggestion would be that you could take individual parts of a car and add a very large amount of detail to them. For example, you could take the engine and add pistons, nuts, bolts, wires, casing, and much more. It would be amazing to see all these itty bitty things fly off when you crash. This was in a game called Motorstorm for the ps3, and i very much like the idea and recommend it. Perhaps even some interior parts like cup holders or a sun visors It would also be fascinating if you could add a third or first person mode to the game so that you could walk around the car you just crashed instead of just moving the camera around. Being able to put the person in the car with a seat belt option would be fun to see. You would see what could happen if you have a seat belt vs when you don't. That would require ragdoll physics. What about fluids? Adding fluids to a car like gasoline or windshield wiper fluids would be cool to see. Thanks for reading! I'll post more if I come up with anything up to snuff.
Everything you said is a great idea but, i think FPS dropdown will be guaranteed. VERY big fps dropdown, with that amount of details.
