Just stopping by because this idea is awesome and Im thinking for a long time how could be possible to go even further and turn SH into a real MMO. When SH5 was released I was convinced that it will be a MMO as a permanent internet connection was/is required. Since then I still keep dreaming about this part but I dont see how we could make this work without Ubi's help.
First of all, we need a server where the campaign files are hosted and shared with the players. Even if we could find a hosting server, would be possible to mod the game in such a way that it will read the campaign files online and not local without hacking the game code and EULA? That way everybody could play on the same map with the same traffic, change intel and form wolfpacks etc... like the real deal.
The biggest problem would be the TC and I dont think the moders could solve this problem even by hacking the game code. Playing with TC1 its impossible even for the most hardcore simers. A solution would to do something similar to PotBS (pirates of the burning sea) where the player can use high TC when sailing free until he encounter/enter a pvp/pve area. Or.. we could reduce the map and play only in smaller area, like North Sea for example. and then maybe we could even use TC1.
The blast would be to combine DC &SH, so we could have some serious pvp. For example, players could perform escort duties for npc convoys by sailing warships and engage other players whom may attack the convoy with subs. Just imagine .. a wolfpack formed by real players attacking a npc convoy guarded by other players
All this may become true in short time because the devs from World of Tanks are working already on World of Battleships where it seems that you may be able to use subs too! And they may unite all their products into a single game, so you could run the war on land, air and sea at the same time. And we are talking about a f2p mmo.. a fine example of smart people doing smart business, exactly the opposite to Ubi.
For those that never heard about WoB, here is the
