You make me choose? Well, I do have maps I really like more than the others.
Out of the maps I've downloaded (very few have I downloaded) I like Ember Island (Genesis119). Problem is, I can't go there anymore because it lags so much when I enter. Or crashes the map server or the game. Shame, because it's such a gorgeous map <3
Out of my own maps, I love my Anamagda map pack (will be public when I finish it). They're all such pretty maps. Except for Malichadsant, which is a really terrifying map.
