Sorry about the gargantuan bump, I was thinking about these really general points a couple of weeks ago, but I've been away in Scotland and haven't long been back. Och aye the noo, whatever that means.
I haven't read through all of this topic, so apologies if anything I've written has already been discussed.
Overall I think there needs to be a logical balance between the alien and the familiar.
If blatant 'alieness' (can't think of a better word) is near constantly being shoved in your face then much of the potential mystery, wonder, and atmosphere is lost imo, as everything is relative. Everything should not be overly alien- how alien something is should depend on it's meaning and purpose within the gameworld. For example, if the devs intend something to feel mysterious or hellish then they could give it an overall alien feel (such as Lothlorien or Mordor in LotR), or if they intend something to feel homely they could give it familiar aspects (such as the shire in LotR)
In TES, things such as daedric realms, dream realms, skooma trips and what not, should feel more alien to contrast with 'regular' things.
Another point is that alieness shouldn't be used at the loss of believability, unless the alien thing is the work of magic such as a daedric realm (Magic should be the only excuse for unbelievability, unless the said thing is meant to be kept mysterious)
Too much familiarity can be bad as well as Oblivion shows. The Crusaders of the Nine (I think that's what they're called) were too bloody similar to the real life medieval crusaders- right down too the appearance of their armour. Their helmets even had the same Christian cross design- Christianity doesn't even exist in the TES universe, so that broke immersion for me.
Plus nearly every screenshot of oblivion could be mistaken for a 3d rendering of a (although slightly fanciful) scene from medieval Western Europe. Influences from real life should be a bit more subtle, although I’d like to see some strong allegoric or non-literal influences from real the real world.
That aside, I do agree that the next game should have an overall more alien feel than Oblivion.
Also, I don't see why some people think Skyrim won't be unique- anything no matter what it is initially based on has the potential to be unique and alien, it's just down to the imagination of the lore writers and concept artists really.
Ugh that was a messy piece of writing. I admit I’ve used the word 'alien' a tad too much. :wacko:
