well it wouldn't be WoW, but the idea of a naval version of WW2 on-line might have some appeal, however that would require ubi to resurrect destroyer command (I didn't have a chance to complete my last post due to the afore mentioned mother demanding a chore or two be completed) however I must confess that the idea has some merit, but unfortunately for such a game to work you'd need some pretty stringent rules on realism and that alone would restrict what would be a pretty small market.
Anyway back to my previous point(s) there were, marked differences in the pacific and Atlantic theatres as well as objectives remember Hitler never REALLY wanted an extended war vs the UK and initially at least he wanted to force a peace, now you can say one captain can't make a difference and that's fine but no matter how onerous the win conditions may be I still feel that if a campaign is going to be TRULY and I quote the back of the box "fully dynamic campaign" then there should be a "win" scenario for the axis even if it is a bitter peace in the west, and as to what is and isn't realistic as a fan of and participant of living history realism can only be taken up to a certain point and then a bit of fun and reward for your effort just gets involved e.g you never heard of Capt Luth having to finish patrol early to go pick up the kids from school, or sticking patrol on pause so he can "pop out and get some milk, or help the missus in"
if you want realism quit your job, move your computer into a damp metal tube buried in the back garden stock it with bad food and move about 20/30 friends in there with you and share bunks with them and only install one small toilet... after three or four weeks living like that (just for that final fear factor) make an arrearage with some "friends" that in the event that you get depth charged in game they should toss a couple of grenades in there and flood it with freezing water so that the compilation of concussion and hypothermia can dull the pain of realising that your computer (and probably most of your friend are about to (if not already) die... unless you'r a technophilic-wizard and have managed to waterproof your computer, in which case your can just get high on the chlorine gas being given off by your cracked battery cells... now THAT is realism
