Actually, I disagree with the premise that mm is too complicted. If a person uses due diligence, and actually goes through the tutorial, a map can be made in a reasonable amount of time. (I think the tutorial is a key to this).
I think that the real time consuming part comes in when the person using MM starts to realize just how closely the map can reflect the actual ground, down to the bldg level. It tends to make perfectionists out of all of us, and before you know it we've invested a lot more time than anticipated.
It isn't a trivial program to use. But it's certainly in the realm of doable. I have pretty meager "modding" skills, but was able to go through the tutorial and end up with a fairly decent map (well, from my perspective anyway).
Could it be easier? I don tknow, perhaps. But often "dumbing down" a utility is difficult witout also reducing it's flexibilty. And that would not be desirable in my opinion. I've taken the tutorials, made a few edits, that reflect my thoughts on the process to follow. I think it might be good to have a little more guidance on using textures. I found my self spending a good afternoon, just experimenting with different textures, and different order of textures. But that was simply because I could, MM made it easy to do, so i lost track of time doing it.
Now having said that, I also would like to see more maps (along with TEMPLATES!) so I support whatever it takes to get folks doing that. I dont beleive MM has been officially "released" perhaps when it is we'll see more user made maps. I'd gladly volunteer to take Stridors tutorial and create a PDF manual if that would expedite the process.
