What i would love to see is a simple game but polished.
Imagine APB, but takes advantage of the A1200 and 2mb, the ability to get out your car and turn it into a Grand theft auto clone BUT you are the police! Better thought out missions, going after criminals, solving cases and eventually capturing mr big.
The gfx stay the same, just add polish.
The closest i came to this was actually hill street blues but i found it very slow going.
