It's back on Greenlight in the number one spot. Free speech arguments sort of make sense. While people do not have a constitutional right to free speech on the Valve marketplace, it also can be said that it is a societal value we like to uphold.
As for the game, it looks like it could be fun, hell even relaxing. Since this is the DF forums, I'll be honest and say that doing twisted things in video games =/= doing them in reality, and that, for instance, playing a first person shooter can be fun and relaxing for a normal person. I'm worried about how the game will handle the difficulty, since they need to carefully balance the amount to which you're attack unarmed people (Mermaid farming anyone?) versus law enforcement/whatever else they have that shoots you.
Now, the developers being Fascist. Erm... personally I think that's really an individual decision, as to should you buy a game that supports it. On one hand I find it funny we see this as a huge issue with this Polish company, when we've all undoubtedly played games made by all sorts of wingnuts. Personally, I view it as, do I like the game? If yes, I'll probably buy it.
I've always thought that fascism, racism, etc, aren't inherently bad. Wait, don't reply yet! Actions are bad. If the Poland decides to be a fascist state, that's mostly okay with me. Ditto if they decide by majority that you've got to be ethnically polish to get in. I draw the line at denying other people what I consider to be inalienable human rights, which I'll admit is a hard line to track. So far as I can tell, these guys haven't really done that. So for me, I'm not worried about them.
