100 surfaces is too much IMO, but it depends. The thing is that you really can't give any hard rules about safe / good poly- or surface count, it's too complex issue to to be "generalized" in any way.
I follow the princle of "enoughness", ie I will use enough polygons to make things look good enough for me, and as low number as possible for surfaces. In the end the code will matter much too, how you optimize entity culling and other gameplay speed related stuff... it's a sort of sum of all the things, and not just one separate part.
