Yes, I think that you can. I may not be Phil, so no garuntee this will work. It is not tested.
Have it so that all player 1 gold comes in as wood, and use negative tribute (paste a minus sign) to get it there to avoid noise. Now, have 2 looping triggers, one for each player:
-ACCUMULATE ATTRIBUTE, WOOD=1
-TRIBUTE, PLAYER TO GAIA, WOOD=1
-TRIBUTE, PLAYER 1 TO GAIA, GOLD=-1
-TRIBUTE, PLAYER 2 TO GAIA, GOLD=-1
Now, just have it so when 1 player spends gold, it will take it away from both.
This will not be instant; it will go 1 resouce point at a time, so if you know that it will only come in a multiple of something, you can make it go much faster. For example, if you get gold 10 at a time, replace the accumulate condition with 10, and the tributes with 10 or negative 10 (depending on which effect).
Or just make it so whenever gold is gotten by either, player, it just gives the same amount to the other player also, then have buying things take gold from both. If for some reason you can't do this, then use the system above.
You want fries with that?[This message has been edited by LoserWithCoolName (edited 10-28-2003 @ 07:04 PM).]
