I originally thought that there was command delay in WEGO for CMSF, I just figured, since I play blue almost exclusively with their whizz-bang toys, the comm systems REALLY worked well.
But I think they are a natural with a WWII setting. It is harder to imagine no delays between orders when comm systems are at best a telephone line or bulky walkie talkie, at worst the fastest corporal that happens to be at hand.
so yeah, gimme Command Delays. let them factor in distance from commander, quality of communication type, commander/squad quality, all that good stuff.
I still think the Take Command Civil War games had the best built in command delay system of any game i've seen, and I didn't find it obtrusive, i found it immersive more then anything else.
