Hmm, personally I thought the AOE3 hc shipment system gave it more depth and strategy. Though it probably wouldn't be appropriate for a game like 0AD. btw, the hc shipments are suppose to complement your strategy, not determine it. Just saying. Anyways, this unit experience system will be interesting. Probably be lots of retreating now. xD btw, do unit ranks affect the stats alot or just a little? (enough to make a very noticeable difference?)
