Zolee, how can you have taverns on all territories? Buildings pricing works like this:
New Building Cost = cost per building * (number of buildings owned + 1)
A tavern costs 10 gold, so the first one is 10 * (0 + 1) = 10, the second one is 10 * (1 + 1) = 20, the 8th one is 10 * (7 + 1) = 80. I'd think that they get rather expensive after a while. If you're spending that much on buildings, then you must be neglecting your army. Oh... I see. You are.
Only 80 gold? lol i usually end matches with 300+ unused gold or more due to the fact that you get the enemy's army if you capture their main territory and i dont have to build any more soldiers by that point, because my army is already so large, the ai cant do anything about it. As i've said. too much gold, too many research points, too many cards. And i'm not neglecting my army, as i've said i keep spamming units every turn and build a tavern or 2 as well if there is gold remaining. The amount of gold you get is insane. Especially when you own half the map. Also 80% isnt all of my territory. I do keep prebuilt buildings just cause im lazy, and i do build about 3 goldmines or so.
