My opinions:
Rugged Lands
It's alright, the builds are a bit eh and the corn is the most annoying. The terraforming is good but all in all I don't think it's a great map. Gameplay is decent.
Asia Games
Yurgh.
Lost Mine
Looks nice and gameplay is fun, but to me is basically Solar Frost but without snow. I quite like it though!
Hell Games
I like this map. Even though there aren't that many structures and terrain is boring, I find it quite fun!
Kharmunrah
I never have chest luck with this and I think the pyramid looks out of place next to the map, but the builds are fantastic and terraforming is great
I don't like the gameplay that much but sometimes it is fun!
Moonlight Lake
To you it might be ugly, but to me it is a fun map. The gameplay is always interesting and fun. The chests are placed well and PvP is very fun!
