I Just had a thread on this same subject.
I too would love to see some WW1 expansion scenarios and mods. Too many people think ww1 was nothing more than suicidal human wave assults. 1914 had some Huge battles for example, the Russian campaign into east prussia had the potintial to be successfull but they were poorly lead. Do I need to mention the desisive battles on the western front of that year?
