I know building the Market place allows for Government and Empire techs. What benefit are the other Market upgrades as they all seem to be about trading. The trading component of the game does not apply anymore does it?

No more trading. Once you have the gold upgrades, your market is useless...except maybe as a defensive structure.

You can recycle some of the gold used to build it by removing it.

if you remove it do you still get the extra income from the techs that depend on you having one?

you get to keep your techs

does that go for all buildings? you keep there techs even after the building is removed?

when you destroy the market you keep the income techs,thats all i know

I don't think you get to do things like buy techs if you get rid of the appropriate building, but if you already bought the tech you can't lose it.

yeah thats what i was trying to say moggy

Interestingly enough, if you destroy your marketplace you will no longer SEE the government and empire techs on your Tech Centre page! If you rebuild the marketplace they reappear, and the income of course, was there all along. I discovered this by forgetting I had the techs, rebuilding a marketplace and then seeing them reappear. Imagine my chagrin.

lol Moggy the tripper hahahahahaha.
Ill bet you had a silent laugh to yourself and then rolled another smoke lol

Isnt' that funny, I did the exact same thing last night

what rolled another somke lol

This is true of the marketplace, you can remove it and still have the techs. However, if you remove the training guild, military academy, blacksmith i don't think you get the bonuses unless you rebuild it. I am not positive on this one though. Anyone got the info on this? I know you can't see them anymore but i don't think you get the bonuses either, ie. advanced armor, advanced weapons, etc.

so I can no longer sell tribute with a marketplace? How much gold will I get back by removing my marketplace that I have already built. I even stupidly spent gold in upgrading my useless marketplace.

You get back 825 gold for destroying your marketplace, as I noticed when I made a training game and tried it... like you should have!
