I think if we could get a few people together a rotary is not that far off or a hard feat to accomplish. I think we should try and make this dead dream an alive reality. XD

Why mess around with a rotary/radial (whatever this car will be called) when we could jump straight to a turbine? Seems like a far more reasonable investment of recourses.
I agree with this thread! We need a rotisserie oven in this game, maybe we could fit one in the bed of a Gavril D-15? Or how about a human sized one in the box truck!
