As long as you don't use sin/cos (oops, no 3D, no polar coordinates, no FFT), sqrt (oops no lenghts), pi (oops no non-polygonal surfaces) or ln/exp (oops, a lot of things are gone there).
Working with rationals is not that realistic nowadays except in things like mathematica, maple and friends. Fixed-point though is still very realistics, it's just a different precision/scale tradeoff than fp, and one you control.
