-> 1000 Corpses: not the worst map in this list. Terrain is acceptable. Keep it.
-> Frozen Canyons: the idea is visible, but the terrain is boring. Too much ice. Remove it!
-> Game of Thrones: no iron, but only little arable land + onesided. Remove it!
-> Game of Thrones 2: the same. Remove it!
-> Heroes of Might and Axe I: it's a fun map, there is nothing wrong with this idea. Sure, the water surface should be flat, but please don't only keep maps that can be played "seriously". After all, gaming shall be fun. Fun maps are part of that. Definately keep this kind of maps! But this one survives only because my list already contains 8 maps to remove. Keep it.
-> Heroes of Might and Axe II: basically the same. But more symmetrical and terrible terrain. No need to keep this when v1 stays. Remove it!
-> Kaderto: more or less the same as the Heroes-series. But more one-sided. Remove it!
-> L-O-S-T Survival: Hmmm, stone
Another fun map, others are worse. Keep it.
-> Open World: Terrain is a no-go. Remove it!
-> Roads: Compared to the others, it's one of the best. Keep it.
-> The King's Favourite: finally acceptable terrain. But this is so extremely onesided, no need to offer this as a 1on1 map. Remove it!
-> Time to Die I - Swamp: another acceptable terrain. Nice to see limited resources which make the map hard. But then a linear gameplay? In a 1on1? Because of the quality of the terrain I'm tempted to keep it (especially compared to the terrible terrains of others), but the map idea is not coherent. Remove it!
-> Tundra: the only map of this list that I had played before. It's symmetrical, but not exactly fair. Still that's a chance to balance different player skills. Keep it.
