Used to buy some games from Direct2Drive. They were great, cheap and worked. I could download the install files and keys and install on all the machines in my house. Then they got bought out, keys didn't work anymore and you had to re-download everything again. I went to Pirate Bay, downloaded the iso's and used my Direct2Drive keys. They never mentioned when I bought the games that they could ever disappear.
I never trust them anymore. I have hard copies of those olser games. I only really play World of Tanks now. Since that one is pointless without the servers... well.. if it dies, I find something else to play.
