I just wanted to let you all know that Sins of a Solar Empire: Rebellion Beta 2 seems to run VERY well under WINE, activation and all
I recently started using Fedora exclusively, and after working through some self inflicted issues I got it going no problem. The only oddity is that if you don't run it in a virtual desktop it wants to only run in 1280x800 or whatever. In a virtual desktop it behaves perfectly. I haven't played any very large games, but small short ones are no problem at least
