I confess. I'm a noob.
I spent tens and tens of MILLIONS worth of resources and maximally i could grow in 2 day's was 150k points and for that kind of growth you have to try and work really really hard.
In this game i saw players growing 100k per day (it's possible if you collect resources and do everything in one day) but i'm always puzzled when i see player growing over 200k points
Sure this dude had HUGE war income but checking him i can see that he built in average (maximum) 10k army per province
So let's do the math. 15 provinces = 150k cavalry
Is that close to 240k points i have no idea and by no mean i'm suggesting this player is cheating knowing he must have really huge war income. I'm just amazed how some other players do something that i just can't no mater how hard i try.
Kudos to them from humble noob
