I support many things that have been said here:
- having a customizable "favorites" selection would help immensely with clutter
- more categories would also help, and it would help if they weren't mutually exclusive. Examples of this kind of categories would be "naval", "co-op/scripted", "Gaia enemies", "geo-realistic", etc.
- I also agree that a general review of all maps would be good, because some maps are just very bad and nobody likes them, and also because some maps are good (even very good) but could be better if some flaws were addressed. Uknown, for instance, can have issues with wood distribution that mainland and continent don't have.
I think Marmara is less balanced than Red Sea, south team has a noticeable strategic advantage. Red Sea is less predictable, and flexible team strategy is necessary to turn the game around. Lower Nubia is another ridiculously unbalanced map.
