Steam Sale Dom3 players might like.

[AstralWanderer]

I purchased this about a year ago, found out it required online activation (*without* making it clear on the packaging) and sent it back. It's bad enough having to deal with CD checks or cardboard codewheels, but online activation means the program dies when the servers shut down (see Shamus Young's Authorization Servers article for more on this).

Steam has its own problems though - as well as its own online activation system, you have all your purchases tied to one Steam account, meaning that it becomes very possible (and very profitable) for Valve to slap on an annual (or even a monthly) fee to keep accounts open. Who'd refuse to pay a $10 monthly fee if it mean losing access to several hundred dollars of previously purchased software?
