Imagine if the formation combat system was improved and made more tactical.
It could be played less frantically and allow for more maneuvers in the battlefield.
I'm not saying it should be slow, but it should allow you to relax while supervising a fight.
In all video games, biomes build a world and an adventure.
For example, Legend of Zelda has that in mind, desert, snowy mountain and ocean (sometimes a lake). It also has a European-style forest.
Maps can tell stories and secrets.
Random maps couldn't have so much detail and ruins and pretty objects.
Add things that are not the same as the random maps.
Try to make them varied and have different mechanics, something that helps is making a 4 season pizza .
Random maps cannot have more than one biome.
What about 4 season map?
