im making about 15k in trade and about 15k in tax

no its not too much, im making 30k a turn and spending about 22-25k AND with how fast u tech up when u start to expand, i cant afford to build everything everywhere, also i only have like 3 full stacks wandering around so short answer no i dont think its too much

my biggest worry is that i cant go to war with any major european factions, im trading with like all of them and if i go to war with any of them ill lose that money. and my income will plummet, the large emphasis on trade income makes it hard to fight wars :S
