Dean, welcome to the CONSIMWORLD Social website!  I was entranced by RING OF FIRE back in the day as it was (I think) the first game to deal with its subject and did a solid job of it.  I also enjoy the WAR STORM platoon level tactical series but haven't cracked into NORMANDY: THE BEGINNING OF THE END yet (it taunts me from the shelf!).  Also enjoy the other games/series you mention although I don't get to play them opposed and mostly do them solitaire.  Hope you find some groups you like here and will make some comments; if you don't, consider creating some groups of your own!
