Maps and mutations do not = entire new landscapes, new races, enemies, effects, companions, factions questlines, etc etc etc.
I'm not even going to get into how the two games read data differently.....or how they play.
you get my point.
Actually, yes they are...
New landscape are basically new maps, new races, enemies, effects, factions are basically like mutators and new skins...
Still, yes, there are going to be mods that cannot be converted to consoles, mostly the ones that does not come in an ESP/ESM (or whatever file Skyrim will use) form...
... makes me think if texture replacers will be included...
