I posted this on TESFan but I'll repost here:
I think it would be far easier on Gamemasters if Akjosch made certain ores only available in certain biomes (in high densities and low commodity of course), rather than generate no ore and have it be hand placed by Gamemasters.
We all know that the moment a hand made ore vein is discovered it would be stripped clean within the hour.
Not only that but they'd be really hard to find unless you made them suitably common or really obvious, yet again putting strain on Gamemasters who'd likely rather be building dungeons.
I also don't think wood or dirt should be a limited resource, it merely reduces our ability to generate varied and interesting biomes such as oases, equatorial jungle and swamp.
It sounds like Akjosch has this mostly figured out so we should probably just do whats easiest for him so that his designs can be realised.
