The answer is: It depends.

RFB is perfectly acceptable for mission play, but the missions themselves must be compatible. For example, missions included with RFB will be ok, but stock missions, which feature different ships, or versions of ships are going to result in a CTD.

This applies equally to missions you yourself create. If you want to create a mission to play with X-Y-Z mods, you should build the mission with those mods (and only those mods) enabled in the game. Otherwise, if there are differences in the units present, they may cause a CTD. The game is very fussy about the exact names of units, the different rosters, ship types, dates of availability, etc.

I hope this explains it well enough. Tbh, I couldn't give you an exact list of the things that cause problems in this area, but I've had the same thing happen when I forgot mission X was developed with a different mod assortment than I had at the moment.

Looking around my mod files, I see you are right. There are no missions included in RFB.

I usually play RFB + RSRDC, so the missions I was thinking of belong to RSRDC. Honestly, I do not play missions, apart from the ones I create myself to test things.

I think most mega-mods will include missions, but in any case what I said goes. If you try to run a mission that, for example, has a ship that is no longer in the roster file that your mods have, the game will crash.

Why are you interested in the missions?

Do you not want to play a career, or just want to learn the game first?

Unfortunately, there are not really good training missions for the game. The stock torpedo attack mission is awful, and I'm not sure the others are too useful, either.



I learned about all this in two ways:

1. Just playing the game. Quality is more important than quantity here. In career mode, I'm serious. This doesn't mean I don't make mistakes, but when I do, I learn from them, so I can do better next time.

2. Reading about real-life WWII sub operations. My personal favorite is Richard H. O'Kane, but there are quite a few good authors to choose from.

And, of course, you can always get answers to specific questions here at Subsim.

You're most welcome.

You don't have to pressure yourself to become expert in the game's mechanics. (We are all apt to lose sight of this, at times.) There is no reason you can't learn different aspects of the game as you go, at your own pace. Some of my most enjoyable times were with the earlier SHCE (SH1), when I knew next to nothing about sub ops. Learning new things about it all was half the fun.
