I'd just like to say, I agree completely with Undertakr. There are games I will not buy because I got ISOs of them from a friend, and tried the game myself. The Sims is a frustrating, pain in the *** game. Its popularity defies belief.
There are also games I *will* be buying, because I got copies of them from a friend. I would never have even considered buying Aliens vs Predator 2. Now, I plan on grabbing a copy next time I'm at Fry's. Heh, I even almost convinced my friend to buy it too, but he didn't like it when he found out there's no gamma correction in it. :/
And yes, games are too expensive (and often not worth the money) these days. ~50 bucks for a game I might not like? I'll wait til it's down to 20, or borrow it from someone.
Phoenix-D, ~300MB is a lot of space?

You can cut it down to ~165 if you don't copy the demos to your hd, and SF still works.
