balance of polity

That's because at the moment expanding your borderes is crucial to expand. I am going to rebalance things in the future updates so that building a lot of settlers would be at least as lucrative as expanding your borders with culture. Therefore agressive people can put their extra resources into settlers to move towards expansion. But honeslty current system is just random bits used to see if the game will "click" at all. Currently it does not have ANY balance. I am planning to make serious changes to the ballance to make the expansion only one of the possible options, not top priority for everyone.

For example I've already adjusted limit of science spendings in Shrine of Knowledge to 1% down from 5%. With such change, pumping up Shrine of Knowledge now is the top priority as now 1 level of Shrine is equivalent on upgrading ALL income buildings up to 1 level. To offset that new power I've also added various requirements for different levels of the Shrine. This way person who is focused on Science will be more inclined to upgrade the shrine and income building up to some decent level first before investing into Chieftain Hut lvl 10 and settlers, thus expansion suddenly becomes not #1 priority.

For war path I've made some tweaking too to reduce the need of new town. I've increased the time to train a brave up to 1 hour 20 minutes, but reduce time by 5% per each level of Hut of the Brave. This way with level 10 you will train braves faster by the factor of 2, but on level 20 you will be building them 20 times faster! Therefore for agressive people upgrading their barrack buildings will become more important than building second town as they need to upgrade their barracks there too in order to churn out units at decent speed.

For warrior type of account army is their main source of income, thus they need to regenerate it fast. It might be not obvious now since there are not many players now and all of them are pretty active, but in real game there will be accounts with different activity levels and significant part of them will be not very active with a lot of excessive resources. Those will be used by warriors as a source of income. Due to the fact that warrior is plundering others non-stop he will have a high chance of loosing units due to accidently meeting resistance. That's why speed of unit training will be critical as in this game we have army limits that are easy to reach.

Naturally, the warriors will be spending resources to upgrade their barracks and other infrastructure required for the barracks (storage, etc.) Upgrading them to the high levels is not cheap.
