I just gave a try in SP to a mod who looks very fun:
http://z7.invisionfree.com/Dom3mods/...?showtopic=573
Everyone start with the same poor nations with H1 and mage 1x.
But most of indies lands have some magic sites (already up, no need to site search) who spawns some random indis (troops mages commanders...)
I think in a tower map this mod could be simply awesome.
Since it would be a very different game with this mod active, i will only set it up if almost everyone want it.
