Now if only you can get one of your friends to buy the game.

Demo's have been all about one player, one level and limited availability of what you can do. I was playing Mortal Kombat Shaolin Monks demo the other day only to find out that the gore on the demo has been toned down to Hello Kitty status. Anywho that is not the case with the upcoming game Sacred 2: Fallen angel for PC.

Sacred 2 will include a full copy of the game for your friends to try out for a full 24 hours. This will include all the maps and multiplayer maps as well asall the options that you will find in the complete game. 

"Rather than showcasing only a limited character or content selection, as most traditional demos do, gamers can share and enjoy the full game experience, trying out the features that most appeal to them, and getting a true sense of the full game."  said Mario Kroll, director of marketing and PR for cdv Software

After the trial period, you can choose to uninstall the game or purchase it. It is as simple as that.
