Pomazok1329, where do you get the Polish maps? Do you read Polish forums or even participate in discussions there? National player communities (like the German one) often discuss interesting locally made maps, but when there are no English versions, it's quite difficult to understand which maps are worth playing, how to play them, and automatic translation in browsers (especially with a large number of errors, typos, and abbreviations in messages) often produces difficult-to-understand text.
I sorted them all by size because usually, if a map is large, it also has a plot, events, and is generally interesting... almost 95% of the first 100 maps made it into the "best" collection. So, I didn't specifically look for them.
But there is a Polish forum, and if you want, I think you can find a lot of interesting things there in terms of maps.

But in reality, Polish maps (like Polish shooters about World War II) don't impress with their quality or interesting new features, so the above is more of an exception to the rule.
