I had basically given up on Assetto Corsa on my Xbox- not enough tracks, samey cars, etc... and then they drop the first Porsche pack on us outta nowhere. Oh my lord, is full boost on the 917/30 (Achtung! Turbopanzer!) fun. And the GT4 Clubsport is more fun than it has any right to be. In any case, I might actually play this game some more.
Until of course the Forza Horizon 3 Porsche pack rolls around.
