Well.. My idea for the game would be- Since I don't think anyone has suggest it.. Be able to upgrade your buildings.. I mean yeah, it's cool you can upgrade your Unit's, but I would like to upgrade my buildings.. Faster mining Productions.. Building limit(Because, to me it's horrible to jut spam buildings and not know what the bloody heck you're doing.) To put it simple.. I want to be able to upgrade my CC(Command Center) to be able to upgrade building limits.. Having it have a Unit or two.. Of it's own. That and.. It's best(In my opinion..)that we should be able to get more building upgrades instead of spending what's left of our little bit of money we have in-our pockets-to buy in-game currency to get the things we want.
