(Read this before you start questioning things)
I have not seen any thing to do with colonisation and just the start date 1440, so I decided to do that.
What this mod provides:
Only England, France, Portugal and Castile colonise. (for a 1,000 turns before cancer starts)
Tribes are not ignored. (Not 100% true)
Some events. (more for the future)
France does not die immediately. (Not 100% true)
Creation of dutchy of Prussia, polish - Lithuanian commonwealth, Spain and Tsardom of Russia by events.
Ming is weakened a lot. (+ Civil war which is hard btw)
