Has anyone spent time converting any of the MMRPG adventures into other editions? Or, perhaps they are vague enough that one can run them in any rules set?

I downloaded the MMRPG modules long ago but I'd much rather run Blackmoor with OD&D or perhaps 5E and so I've never really used them or even looked at them much. My son and his friends were asking about me running a campaign for him and I thought, "maybe Blackmoor!"

I have the full d20 Blackmoor product line, too, but have never really been a d20 fan. I guess that's why I'm wondering if anyone has done the "heavy lifting" to convert any of the modules.

Also, while I'm at it, can anyone tell me how long it typically takes to play through a module? If I run a bunch of these for my son I'd like to have an idea what sort of time block to schedule.

Thanks for the info so far. Most of the time I can "wing it" with 5E, but it's not nearly as natural a process as with OD&D because of the details. I know that 3E/Pathfinder has a LOT of details, so ignoring stuff makes it easy to go backward to OD&D but I'm not sure if it's as simple to go forward to 5E. If that makes any sense.

As part of Blackmoor Living World campaign on RPoL () the MMRPG adventures were converted on the fly to Advanced Fighting Fantasy ruleset (here you can find some more detail about how Blackmoor was adapted to AFF: ).
Of course, this is a conversion to another ruleset, rather than to another edition (of D&D).

I've run a couple of the MMRPG episodes as OD&D. Some of them are really pretty cool (others maybe not so much). For me (and I think for you Fin), the trouble isn't converting the stats of monsters and such, it is the format itself that is somewhat challenging. The "episodes" are quite verbose with background and Q and A response material. I guess the idea is that the game is scripted from start to finish for uniformity. The actual adventure is usually fairly short. Personally I, read the whole thing to get familiar with the idea of it, go through and circle or otherwise mark the key encounter info, print off the maps, and improvise the rest when I run it.

Personally, my experience doing this has been very positive, so far! ;)
