Inspired by fake projective planes, this talk concerns normal projective surfaces whose Qhomology equals that of IP^2.
I shall concentrate on the Gorenstein case of numerically trivial canonical bundle which is closely related to Enriques surfaces.
In the complex case, I will give a complete classification of their moduli which turn out to be rational, 1dimensional and defined over Q.
Time permitting, I will also discuss subtleties in positive characteristic.
