I've thought about Vietnam for a bit, I'm curious what you come up with in terms of goals and abilities.
Starting date: 257 BC @ Co Loa (Hanoi)
Leaders: Thuc Phan, Trung Sisters, Le Loi
UP: Power of Guerilla warfare: (Fully) fortified, hilled and forested units have 2 first strikes.
(It will be a challenge to code it properly, but I'm looking forward to it)
UU: Rattan Archer, replaces skirmisher/longbowman (Additional first strike, 10% higher withdraw chance, collateral damage to 1 more unit)
UB: Dinh, replaces Civic Square. Probably free City Garisson like HR.
UHV1: Have 8000 culture by 1200 AD
Inspired by water puppetry
UHV2: Get 3 Generals by 1500 AD
This UHV is meant to represent the wars between Vietnam and China. Especially the tale of Le Loi. (I was inspired by the AoE II Vietnam Campaign)
UHV3: Do not lose a city by 1950 AD
This UHV is meant to represent the Vietcong and also a bit the wars with China.
I will change China so it will try to invade Vietnam.
