I just installed MOI3 beta on Ubuntu linux + wine and it works great (no wine tricks, no special setups). There is a little bit of funky "noise" streaks that occur when i change views, but it goes away as soon as I click something. Also, when you mouse over a line and it highlights, it doesnt like to "un-highlight" which gets weird. Otherwise it works ok.

on the note of supporting linux, I would rather see more development of the product rather than re-development to support linux. I only use Linux because my (good) computer failed and it might be a while until I can replace it. Until then, I am rockin' MoI on an Ubuntu Laptop. Woohoo!
