Truthfully I'm looking forward to the ultimate TAM in BtS rather than Civ5. The map scale is really too small (meaning each hex is rather a large area), to only allow 1 unit per hex. I could handle a limitation of maybe 5, 7, 9 or 12 units per hex depending on map scale. The only way to effectively make it a tactical level game is to have a zoom in mode for battles where you get to arrange your units, give them pre-ordained orders, etc.
