Old Model/Camera
I'd like to see the old camera make a comeback as well as the old tori/uke model (the lower poly ones) as an option or possible /opt command. Assuming the texture layout is the same with the old tori-model, I don't see it becoming a problem since it's client side. As for the old camera, the only problem I see is the newer options like free-cam. However, if you're enabling the old camera, you probably don't care about that option anyways.
Camera:
Toribash 3.66 (the old camera)
I'd like to reiterate, this would be a client side option and the new model would be the default. An opt command or having an option for the old camera/model would be great for people who enjoyed the old look/style of toribash.
