I know originally that Stefan told me there would not be a v4 for Linux, but I'm glad that has been changed. I use my linux box religiously. Actually, of the 4 windows partitions installed on my desktop, somehow zero of them work
My laptop sadly has an intel i810 which does not run openGL for crap, so looks like when there is a v4 for Linux, it'll be played strictly on my desktop. I did play it for Windows a few times (mostly restarted just to test it), and it was nice. And now, back to hibernation for me.
