The most challenging maps for you.

Lider1, "Gift-2001" is only difficult the first time. But once you know in advance what, where, and how, you can complete it without much effort. This applies to any map. But for me, it's already not interesting: I'd rather play a new map than "play to death" one I've already completed. :)
Chingis, is there any hope that you will one day achieve the desired best result in completing "Champions of Gelia" and turn your favorable attention to other maps? After all, there are more than 3000 of them! ;)
