silviucc: I did have a Season Pass for it but that did not give me all the DLCs (wasn't the point of a Season Pass to do just that?). Anyway, I'll be sure to buy some DLCs once it's out. Civ 5 for Linux turned out great, I'm confident this one will be just as good.
The season pass only stated that it would include the first four campaign DLCs, they didn't really rip us off or anything, but they did take advantage of the game's success and released a whole bunch of other paid DLCs after that. Well, I can't really complain because I bought and enjoyed all of them, but this game bled me... :) Anyway, it was on a -75% off sale during the Steam summer sales, including all DLCs, so I just rebought it then (didn't even know if it was coming to Linux, but was hoping). You just have to be careful not to re-buy stuff, because if you have the season pass it will let you buy the DLCs it includes seperately etc.
IMO, this game is totally worth the money I spent on it, I got my entertainment. :D I'm so glad I'm going to be able to play it again with better graphics this time.
And yeah, Civ5 turned out great, and Aspyr is also doing the BL2 port, so I'm having high hopes for it!
