Legally no less. Atari is offering the full version of Temple of Elemental Evil over Kazaa which includes six hours of play. If you decide to keep it you can pay $50 bucks to unlock the sucker. This is a great way to get the game for those of you outside of North America with fast connections or too lazy to hit the store. I just got off the phone with Atari's PR and they had no idea this deal was going on so it may be something they arranged through their OEM branch.
Anyways, head over here to get the details and obviously you will need Kazaa (I'm told Kazaa lite works too) to download the file. If you use Kazaa lite and the web page download link doesn't work try to load it within the Kazaa Lite web browser.
