I really liked AoW 1, shadow magic was frankly a bit of a let down for me, but still very cool, I might be able to help you with some unit graphics, not ships or siege weapons, but for those you should look through a bunch of other mods, I've very sure I've come across 1 or two mods that have some artillery in dom 3 and 1 or 2 in dom 2, Oh! one of them is on the illwinter home page (
http://www.illwinter.com ) it's a two nation orc one.
But anyway, you can give me some tasks with units and I'll do my best, if you wanna see my previous work check out the "Pirate Nation" it may be on the second page by now.
