You ought to take snapshots of each female pedestrian model. I did the same but with the wildlife, however there are more female peds than unique animals, so you should have yourself a decent album by the end.
World is moving fast.Won't surprise me if this is legit. Rockstar are having to ditch singleplayer to keep up with today's industry; the shallow, instant-gratification culture that Rockstar have themselves pissed on over the years. Shame they are now realising that in order to keep afloat, they will have to give up what made them stand out, and simply conform like the rest of the mindless companies out there (EA, Activision and the likes of).
Singleplayer and GTA go hand-in-hand. Always has. From the plot, to the exploration to the replayability. I prefer an interesting campaign that I can lose myself in, than a generic situation of just shooting internet folk which can be achieved in your typical FPS.
