There was no real reason for the change. There was no real benefit for the change. The change itself was senseless and damaging to the foundation of lore, because now whenever we have a discussion about future titles and where they might take place, we have to deal with the nagging question of, "Well, who's to say Bethesda won't just say 'screw this' to the really unique things established in this location? Who's to say they won't just start changing things just for the hell of it?
The reason for the change was to make the world more believable from a human point of view. If we see jungle next to tundra, something nags at our brain telling us 'this isn't right'. And yes, there is every chance that Bethesda will change the lore of other provinces for future games, because TES is such a young and unexplored fantasy world compared to others, that much of the world's layout and history is still relatively unknown to its makers. That's why i'm saying it shouldn't be taken so badly that Cyrodiil was altered, and we should even expect similar changes in the future to other unexplored areas.
Darkstone, what you don't seem to grasp is that Nirn ISN'T AN EARTH-BASED WORLD.
It is an Earth-based world. You can't deny that.
As for the climate argument, even though i agree that transition has to be present to create a believable world, what you aren't getting is that TES doesn't have to be a believable world, if TES was desert to the north, and tundra to the south, would it make sense? No. Would it be ok? Yes, because it is made-up, it is a fantasy, even though it can act real it doesn't have to be, and this is the crucial point you are missing, just because it looks real, doesn't mean it needs to be real.
Ok I can agree with you here. TES doesn't
have to be a believable world. But I much prefer fantasy worlds when they are believable. When I can look at them and say "
Wow, this could really happen. It all makes so much sense within its own lore that I can really immerse myself and see this being a real place somewhere." When you have conflicting biome locations, the world becomes harder to believe, and loses immersion factor. Sure it's all subject to opinion, but this is the widest opinion, which is why this method of world creation is used by almost every single author in history.
ThatOneGuy and UnknownK: You've both made some great points here. I can certainly see where you are coming from, because of course it is all subjective, and you two are happy to look at this world without question. You see it is as: whatever is there, it's there for a reason, and despite it not making sense in our world, it must make sense in Nirn, or it wouldn't be there at all. Am I right here?
I have a very logical mind, and a strong education in Ecology, and so I need a world to make sense to be believable. Hence my strong support of an Earth-based fantasy world needing to have a coherent geographical layout, with inconsistencies being well explained by lore. As far as I can see, Bethesda didn't put much thought at all into biomes when they first created Nirn, and strongly felt the need to correct this with Cyrodiil. Otherwise the change wouldn't have been made. So hopefully you're starting to understand where i'm coming from too. I'm not making things up. If anything i'm just taking everything one step further than you. ^_^
