The Protectors of Etheria is a stand-alone mod of the game Warlords Battlecry 3 (i.e. it can be run without having the original game installed - 100% free full game). It is an improved RTS/RPG game with new campaigns, quests, terrain, units, items, heroes, modding features and more. Beta versions available for download!
Map making has never been easier. Coming in 0.8.6
The grid only shows up when placing something down that has a grid of its own (unit / building / feature), so it's not always visible. I personally like it - it's interesting to be able to see exactly where a unit can move. Many times I have purposely placed small rocks behind trees just to prevent a unit from walking there. Now I can clearly see exactly where a unit can move to and where to put my obstructions!
This also helps in making sure there's enough room for the larger units to pass though those smaller gaps.
And of course, this option can be disabled/enabled by the user freely.
