Hello,
I can't answer your question about the MOD's because i have little experience with them.
The game supports multistation multiplayer up to 4 players in the same sub:
- control
- sensors
- weapons
- TMA
The game is stable in multiplayer, or at least it was not an issue to me.
I would say that the minimum game length (with exchange of torpedoes) is around 20-30 minutes, given the (insufficent) distance at the start.
If you have experience with Sub Command you will need relatively little training to play at a noob level, but that applies for the subs only of course.
If you don't have experience with Sub Command you will need to practice some hours in order to understand the game mechanics. My hint is to not open the book unless your learning process is stuck. Further, I encourage you to post your "problems" in here (if any). The people here will usually go much farther than the book and maybe add valuable hints/tricks.
For me personally the frigate was the most difficult unit to man (never managed at present
)
The first problem you might encounter is to open the requested ports on your firewall/router (if any).
