I have about 30 of each resources building, and of course im makin a fat stack of resources everyturn. I started upgrading each building before and I found that it seemed a little expencive.

With buildings that have 20 turns left or so, would it be a good idea to upgrade everything?

I'd say rite now half the buildings are upgraded but there's still about 40 left to upgrade.

how about you just calculate it? example: a goldmine upgrade gives you 250+ every turn and costs 2500 so after 11 turns itīs worth it.

generally 20 turns is worthwhile.. Upgrade the highest turn remainings of each type first. Gold mines are most important, gem ponds are generally least (if you have all the techs you want they are only needed in large quantity for upgrading barracks).

like Vivache said.....jus make sure that when you upgrade the cost is less than what youll get in that amount of turns.

I personally only do it if it doubles or triples the amount im spending.

I often do it to my gold mine. If you think you're going to use a lot of metal, upgrade that early too. Otherwise I don't upgrade anything else until they regenerate after turn 40. I find it's usually best to spend money and resources elsewhere early on. Remember also that if you can't defend what you've upgraded, then your opponent gets the upgrade advantage when they take over your resource buildings.

this kinda goes in to my general thought:
"don't build or upgrade you can't control or defend"
just upgrade those resources near your castle. the others i usually leave to the norm. as for when it is feasible, they said it..do the math. if you can afford it now..it will pay dividends down the road.
late.

you can upgrade resource buildings? whoa..
