Ok after playing some of the maps just for getting a view i think most maps had a nice terrain, i especially liked the terrain of RunningAway. Unfortunately i didn't like how his map used a lot of slang and was rather simple. The spells were good however.
Micromania was good too, it had a very good interface and nice ideas. But the fact that all heroes have the same class and only like 3hp at start was quite annoying. You could die very easily and a few more heroes would've helped.
SniperWarfare was a bit simple...no spells just shooting...also you could shoot team mates and get points for it! It was a bit boring, needs like spells or classes...
Warcraft Arena had simple, yet nice terrain. The arenas were all without any cover, height differences or anything like that which made them a bit the same except they had different terrain. But that was not really the problem. The problem was nearly all heroes and spells were non-modified warcraft 3 heroes, which was VERY disappointing...
I am surprised by some of the good ideas, terrain and spells, but I was shocked that none of the maps had any Help(F9) and some units were just too standard.
Overall good job to most maps.
