Will there be any grassy areas? Fields? That aren't covered in snow?
I'm not really sure what the lore says about this, so that's why I asked. I think there really should be diversity in the environment. Morrowind had a very nice such one.
But at the same time, it shouldn't be too unrealistic. I mean, Skyrim is ... north.
Perhaps a solution would be to have really advanced seasons? Causing otherwise most snowy areas to be grassy in the summer? Then again, I have no idea what's the engine's like, and if it can accomplish this. Although I think that if it could do this, it would be purely awesome.
