As it is, MTW2 very much tends to turn into a development race; I always try to produce armor and weapons upgrades as soon as possible to stay ahead of the AI. Which is a shame in a sense, because it means that usually most battles occur when my troops are already fully upgraded. That way you skip the feudal period for a large part, and end up with gothic armor in the 11th century.
Would it be possible to have more events to occur like the gunpowder event, but than for arms and armor upgrades? Like early 11th century you get heavy mail, than early 12th century partial plate, 13th century full plate and so on?
This would be more historical, and it would also even out development which might be good for the AI.
What would I need to do to achieve this?
