I think the cultuurstelsel should be better modelled. I'm one of the early contributors of Dutch events to the VIP mod and the current event about the Cultuurstelsel is my idea/work. At the time I wanted to give an increased productivity for silk, coffee and what not (i.e. the local resources) for increased militancy for the local population. The people who at that time where in charge of VIP (Generalisimo and pimparel IIRC) were against it, because in their design philosophy only technology should in/decrease production efficiency. Therefore I made the event so that it increased life sustainability of Batavia (the idea is that the profits of the cultuurstelsel helped the city blossom).
I'd like it when the event is redesigned so that it does increase the production efficiency of certain RGO's and that it increases militancy for the local population. The player would, from time to time, get the chance to abandon or continue the policy. There could also be random events like the Bad Harvest event. Instead of substracting some resources from the stockpile, local farmers should receive a +1 (or whatever value) in militancy, so symbolize that they're having more difficulties because of the Cultuurstelsel.
