there are some multiplayer subsimmers out there.
but i don't think the multiplayer crowd represents a very large portion of the overall submarine simulation community.
Since the date of release i have played SH3 multiplayer ONCE.
personally... i dont really care about SH5 being multiplayer or not.
there are far too many intricacies and issues with real time multi player naval warfare sims unless you stick to a VERY SMALL map segment.
i just never viewed it as being much fun myself.
there are those who disagree but i will make the bold statement that... i think most of the subsimmers out there will agree with the opinion that multiplay is not a core segment of the silent hunter franchise which drives many of us to buy the game.
if this is true about multiplayer not being included... big deal.
