This may not have much to do with the general gist of this thread, but honestly? I wish I could give you a high-five for this part right now. Like you, I am Polish, and the very Polish phenomenon you're describing has been bothering me ever since I got my first serious Internet access.
I do not presume to understand where this extreme gaming conservatism comes from, but it is certainly doubly visible within the Polish gaming community. Or perhaps it is mostly a genre thing? I have no idea.
