My sister got a PS3 and I had a question maybe someone here can answer.

I bought Darksiders & the load times are fucking ridiculous. After I put the game in there's a 10 minute wait before the game starts up and any loading done in the game takes 3-4 minutes. I thought it might have been installing to the HD but its slow to load different levels in-game. Are all PS3 games like that?

Also, any recommendations on some PSN games?
