Well ...
dasriech ... the sim is no longer supported by the developer and as far as I know theres no one doin' ANYTHING as far as mods with it anymore.
http://www.battlefront.com/products/t72/news.html Here you can find a dedicated forum ( little to no activity )and what little downloads there are for this sim.
As far as game play goes ... I like it ... it looks good and plays well. the missions are rather difficult to complete at times and are frustrating to say the least ( those pesky RPG's )and it's hard at times to control the units that are placed under your command in some missions.
But over all I like it and play it from time to time and I enjoy it for what it is !
