#1: Not very easy to mod.
#2: Darkshimmer and the digital-Underground team (including myself), worked on a mod for the game a long time ago called "
Age of War". I found the latest download on ModDB located
here.
The reason IIRC that we quit modding the game, was because of certain limitations which we were unable to circumvent. Been a few years since I last had the game installed even. It's very nice looking, but as I said it has it's limitations. This, coupled with our on-and-off modding of
Sins of a Solar Empire led to us not modding Nexus anymore. These days, we're completely in "modding retirement" as it were. Of the old team, i'm the only one who still visits the BCC forums AFAIK, and The Stress Puppy is around from time to time. Thou he's more involved in modding Sins, on the "
Sacrifice of Angels 2" mod. There's a thread over at their forums (
http://www.sinsofasolarempire.com) where you can find their development.
