Upgrading units

When you upgrade in Brescia you can only upgrade 4 units Calvary catapults infantry and archers you should be able to upgrade more units like different animals and soldeirs like smokers maybe like more modern units

modern in middle age? also suggested before... and they should add my suggested spy...

Yeah I spy like to see whats in the city

Yeah I spy like to see whats in the city

Well... We already have the scouting ability..

but not to see their buildings

whats the differnce if you can see their building or not?

then u can see if its worth to capture them etc

i think that kinda gets rid of some accpects of the game

it will put more strategy into the game

how so? it just gives every bit of information to someone without any way to counter. I say scouting is good enough, unless somthing changes with the 'spies'
