I run it on xp just fine,
However others seem to have a pain in the neck trying

I cant find ANY mods As yet but im Still looking and will be adding them to my shogun web page when i find them (cant do much to page b4 i do)

Theres a built in map editor in STW its in options.

Stick about though some one els may be able to tell you lost more than this,

Personaly id buy it, but i already own it and dont own MTW.
I prefer shogun to RTW but i dont know if MTW is better than shogun.
