Louis, a very interesting concept !

I can see 2 things happening here (and they could both happen in parallell).
What you are suggesting is basically freeing up the pre-made maps of the SP campaign for MP battles. This is something everyone could do without downloading files using your nomenclature. All we would need is maybe a list of what are good terrains to use for this.

At the same time we could have creatively designed maps which would have to be downloaded, but which could have poetic names, like Orda suggests. There may be only a few of them, and perhaps made for special occasions (like tournaments, re-enactments etc.).


I'd love to give your way a try.
What do I have to do after saving [TFO-FLT]_49-98 ?
And can be meet up and try it out ?
