Silabus

Okay, so I've been reading/watching reviews. Seems like a pretty good game but all the reviews say that it's almost impossible to find a multiplayer game. Are these problems still around or were they fixed?

Is there a demo for this game that I could download or will there be? I'm interested in the game but don't buy PC games without a demo because they can't be returned for any reason due to piracy issues. Also how does the RPG element work? Do you lose everything at the end of each round or do all of your stats/upgrades/money save?
