There's IRC (Internet Relay Chat) or Newsgroups/Usenet. IRC is free but speeds can vary and finding things can be tricky. Newsgroups/Usenet aren't free (typically £5/$10 a month unlimited downloads - what I use I got in while they was running a offer so it stayed at that price I belive it's $10 a month and then goes up to $12 a month after first two months) and have choice from over TeraBytes and TeraBytes of Games an they download at the max speed of your Computer Connection. You can click the link in my sig if you want to find out more about Usenet/Newsgroup Downloading. I highly recommend Usenet/Newsgroups especially if you have a good connection.

There's also eDonkey/eMule - Slyck.com - Guide To eDonkey2k - Intro
but eMule is pretty much dead and very slow.
