I think it is totally rediculous that they are "selling" this demo.
I have not looked through the 5 pages of posts, but I sincerely hope that "selling" means inclusion of the demo in a magazine. If they are actually charging for a demo, thats just stupid.
The whole reason for Demo's is to promote their game (kinda free advertising). If I cannot try a demo of a game, I just d/l the warez version. If the game is good, I buy it (to get the features like movies, and cd-keys). If it is not good, I don't. (I also don't usually play it through.)
If the gaming industry wants to charge for demos, I won't buy their games.
