Yes it is, it normally starts off slowly but, once you do a few missions and the empire option opens up, its much better. I'm earning about at least $7000 every time the clock hits 16:00 (thats the pay-day time for each of your buildings held). I want to unlock the rest of the island, though. It's boring just being on the one island, going the same way.
Anyway, I'm gonna play Vice City Stories later after I've done both some work and after the Man U game, which is on now .
Lol, I make $81,600 a game day.
I'm about to play Madden 2007, I can't control the QB Vision.
