Just an FYI, D2D now has a 5 activation limit on their games.

So if something goes wrong with the game and needs to be reinstalled or you buy a new computer,

you may or may not be able to play your "purchased" game from D2D.

You can send in a manual activation request however, and you can wait until they get around to sending you

a 1 time use manual activation code.

In my case, I recently purchased a game from D2D and Vista kept failing to save the activation to the game.

So I hit my activation limit and can no longer play the game I legally purchased...

until D2D may or may not send me a new code.

Pure awesome.

Sooo my vote is to stick with Steam or your local Gamespot.
