what could possibly prevent Sergey?
What do you mean by "prevent"? Nothing prevents me. There are just maps that are enjoyable to play on, with beautiful landscapes. And then there are maps that aren't. A continuous snow cover everywhere is probably the worst option in terms of aesthetics.

For some reason, whenever I express any opinion about a map, even something that seems completely harmless – like commenting on its aesthetics – some people immediately twist it into me saying that "something is preventing me" from enjoying it. But that's just not true!
By the way, the map "King of the Minotaurs" was very beautiful, and it was enjoyable to play on. If it weren't for the anti-magic garrison that unbalanced its gameplay, it would have been perfect! I would have said that it was the best map of all the ones I've seen.
