> edit: am i missing something here? those disagreeing, please let me know why you believe you deserve a refund in this situation, knowing that ubisoft only advertised support for windows.

You're probably downvoted by people's emotions and feelings because they don't want to see any (even and especially if valid) defense of Ubisoft here. It's wrong and shouldn't happen, but it very much does.

I'm linux-only for 15+ years now and only buy games that run on Linux. I am filled with righteous rage when companies do what they are doing. But you're not wrong, this one is on the buyer not the seller, though everyone should remember this move and avoid buying Ubisoft games in the future because they have proven outwardly hostile.

A criticism I do give them (the seller) though, if you're going to block linux then it should be well-stated in the game description so people don't miss it. Not doing this is dishonest marketing IMHO.
