ehm, it would be easy yes, but if you earn money as much to upgrade as if it cost you nothing, or other way around, make upgrading so cheap you won't feel the pain...it would be the same as upgrading for nothing at all...rockinroger said:just a thought for warlords expansion. how about a national wonder that reduces the cost of upgrading units. ihate having to reduce research to upgrade my units.
the point is, you must make choices in civilization, like in real life.
-wanna spend money on schools, universities, etc?
-wanna spend money on infrastructure?
-wanna spend on the military?
just like in reality, our military cannot afford to buy 5000 F117, 40.000Abrams and 40.000Leopard III, 4000 Apacha AH-64D..but they can't of course they want all the soldiers to be equipted with highly sofhisticated infraredcameras, state of the art weaponry..but they can't..no money..
Civ should make you the leader to make to such choices, if you feel war is not arising, dont upgrade, if you think war is comming, upgrade every unit, or only those near the border, upgrade city defencing units, or your battle forces? choices to be made by you..that's the point of civ..you could also indeed not research 20turns and upgrade everything...
I think Keldath already improved alot by making research more expensive..it takes you longer to research, hence you can safe longer to upgrade units once available....maybe units from the beginning of the game have promotions against gunfire, arrow, melee units, etc..those promotions you normally dont want later in the game anyway, since war is changing..so choose wisely to not upgrade such units and use them as canon food
that's what i do to safe costs and keep research maxed.
