hehe, thats the problem...
You cant run CS2D in Linux...
You just can host a dedicated server on it...
don't talk about things you don't know. Of course you can play CS2DMax on Linux!
With WINE it should normally work, at my Ubuntu PC, it works without any problems.
Like StillShootin sad, try OpenFL first.
however there will be a linux binary for the client too. maybe already for the next release (I don't know when - don't ask!). you'll not have to use wine then.
