This pack includes the maps, which will simply give you the best workshop experience out there.
Some of them have a stunning setting and detail amount, comparing to others. Some of them are simply fun to play, as they fit into that pttr formula. Some of them are very different from what you would regularly expect from the game.
But anyway, If you're looking for the best maps of all time, you came to the right place. Must play tier.

the collection is built up accourding with my personal experience both as a player and as a mapmaker. So the list is subjective.
You see, steam ranking sucks, and many incredible levels have 3 to 4 stars, some of them have no rating at all.
So, dont be surprised when you see 3 stars levels on this list, and give these maps a chance.
