Science cities :
For lil stars :)
Focusing on science from the very start will allow you prepare for Suzerain properly, speed up development and make gameplay much more enjoyable as unlocking crystals, runes, extra heroes, upgrading troops to lvl 4, etc won't be taking 'forever'.
Being able to keep all gates open 24/7 makes 3-4 stars perfect for studying.
Secondary science city setup (43 cells) :
- 1 - 2 towers
- 13 lvl 5 cottages
- 28 lvl 5 labs (25 points/hr each)
- 32 lvl 5 labs in villages (+30%, 32 points/hr each)
1724 points per hour
4 science cities will bring you to 6896 points/hr

Capital :
- inside: feel free to build whatever you currently need (troops, storage, merchants, etc)
- 32 lvl 5 labs in villages (1024/hr)
7920 points/hr in total without BG upgrades
Extras :
- global services: science + 25% in all cities for 7 days 39 BG (which will bring you to 9900 points per hour), you should be able to cover it easily from hitting ruins
- if you live in a safe area, and surrounded by friendly neighbors, you can try replacing towers in secondary cities with extra alchemy labs (+200 more points per hour from 4 cities, 10100/hr )
- chain of quests for finding scrolls in ruins with quite noticeable science boost rewards
- extra cities if you can afford unlocking them (in this case you might want to leave all labs lvl 4 while playing on 3-4 stars, otherwise they won't fit into rating range)
If you are careful with what you build in the capital and leave pricey buildings
upgrades for when you are ready to go 5, you should have enough rating points left to maintain a decent army for ruins.
