I'd like some more fields in glest for example:
- forest: units that can walk in forests, because it looks a bit stupid that forest look pretty walkable but they aint.
- water: Like GAE there could be some units able to swim...
I think that would add a lot of intresting gameplay.
Well, water is now possible, in the latest GAE versions, shown in Military. What you might want is a better way to have ships. A good example is in Rise and Fall. They have ramming, on-ship unit production, boarding, and catapults on the ship. Glest will never be like that, but maybe some of that can be implemented.
