Not enough I fear lol.
I´ve got too many games lying beside my computer. It´s actually lowering my desire to play since I know that it would take too much time to play them all through. I got stuck replicating Toronto so now I play 1-1˝ hours of SC3000 every day.
Dang, it still doesn´t have the closest resemblance yet.
When I got Arx I played 5 hours straight, well almost.
