I am just playing all maps one by one, without skipping, got on Orbis Veteribus Notus and its territory income is damn high! This is the first map I've seen in idle which has real big territory income, it is even greater than bonus income, especially with using artifacts. I thought there will be no such maps, territory income almost everywhere is real bad and there was no use for its artifact. On this map it is a turnaround :D Any others maps like this one?

I had this recently, too. And my current level also seems to be alike. I'm currently at Reconquest and the other map that I discovered this on has to be Far Land (Far Land took ages so it can't be the one before that). In both levels territory income and bonus income are approximately equal (after techs and artifacts, so I don't know for sure what the territory income actually is compared to bonuses as both are somewhat boosted for me). (edit: I don't want to claim that one is higher than the other because this changes with every territory you claim, but I'm pretty sure that I had a moment in both levels where the territory income in fact exceeded the bonus income)

PS: A better comparison is "Money per second" compared to "Money/sec for bonuses you own" on the "Level Stats" (assuming you have the Level 4 statistics advancement). The values on your screenshot are no clear evidence for your actual income, but still, seeing the territory number being (that much) higher than bonus is something I wouldn't have expected.

One or two updates ago, Fizzer rebalanced territory and bonus incomes so that they are more equal now as opposed to the 1/10th of Bonus income that it was. As such, Territory Money Bonus is now significantly more useful than it was. It is possible this is the first time you are playing on one of the updated maps.

Oh, right, it may be this. Previous map was played with very little income from anything, so had to sell lots of items, now I am rich right from the start, lots of money, but little army income :D
