I love Bit Torrent, although I always pay for my games. I think the only game I ever "warezed" was Alien vs. Predator 2 Gold - which I just wanted to try out. I ended up buying it from a bargain bin for like $4.99 or something.
BTW, Bit Torrent and P2P is not illegal. It all depends on your purpose.
I use Bit Torrent most often to get large Linux or Open Source ISO. I have 3 or 4 tracker sites I check such as SuprNova, etc.
