It wasnt all that difficult to me, but I got bored after a little while. I think that maybe I should've spent more time playing it, but I just couldnt get into it...
I just think it was too much of an arcade style game, and i'd rather play something more realistic. The controls were what I had to spend the most time getting used to, the other thing is the graphics werent really that good. It uses the same engine as GTA, but some things just didnt look right to me. I wasnt very fond of the soundtrack either, it just didnt help me get into the game.
