Heres a strategy:
1.Start as gaul king
2.Make your focus on building crop fields and no res fields in spawn
3.Prepare to settle next village ASAP (with the town hall quest) right next to first one
4. Both villages should have some basic infrastructure like few lvls of marketplace(balancing res between villages and keep trade route from second village to first with all res earned) and lvl3 or higher if like barracks (both village making phals fills oasis quite quicly)
5. claim oasises with both villages and try filling with phalas ASAP (good if first village has 50% crop like I got luckily,,second village wood and crop--wood you can easily trade for iron if not clay too and sometimes with earning from trades since wood is most asked for)
6. Build all crop fields to lvl 10 in spawn so you are still under BP ..WH 14,Granary 20, grain mill5, bakery some lvls too
Being king is good for tribute if lucky with governors and no need to focus on off troops yet since no robbers
stay under bp until enough troops to come out safely and develop rest fields then
Luckily I got mercenary helm and gladiator helm with quest so I sold them for sum 10k silver so I had no problem with gold
Think of a strategy to take from that point on
Im thinking that its a reasonable way to just take villages for the idea of developing only one res with corresponding oasis so like 5iron village with lvl1 clay and wood ..crop is good. This way you make more bang for the buck and will get to optimal total income faster since all the specialized production bonus (dont develop fields that have no oasis bonus is the basic idea of this)
At the moment im on speed server ..only 1 crop field at 10 this point , but my crop income is about 5k..estimating when all oasis full and fields at 10 or above, my income is at least 8-10k while still under BP
