Thanks Tengen, that is reassuring to hear.
To continue on a side note, I'm surprised at the parallels between the Guild Wars mythos and TES. Guild Wars 2 will be set 250 years after the cataclysmic events of Guild Wars, and the 5 or 6 gods are noted as having become more distant from their creation. If there is a TES V, it will probably be set 200 years after the Oblivion Crisis, and the Aedra seem to have been distant from mortals for a long time, even during the events of "Morrowind" and "Oblivion" (though you do see three avatars while playing MW). The final expansion of GW was set in the far North, including a Nordlike race (though they're also giants and shapeshifters), while TES V is rumored to be in the similar region of Skyrim. Well, maybe most of this is coincidence.
I'm just going to butt in. I don't mean to sound rude or anything. You keep talking about how Guild Wars and Elder Scrolls are related, for the simple fact that their next installments happen a few centuries later.
To be honest, what I see is no direct relation, but just a common...I don't know the best word to use...plot twist maybe? Basically, a device used to change around the traditional setting. Accomplished quite well between Morrowind and Oblivion, which are radically different based on setting alone. Skyrim - if the case is that Skyrim the next game - is just snowy Cyrodiil. You need to change more than the region for that to feel like a new game.
If you must compare ESIV and ESV t a different series, I'd say a better example to use is Fable II, an amazing 500 years after Fable I, where the world completely changed. A little too much, in my opinion, because it feels like nothing from the first game actually happened aside from wall paintings in this one room you spend a good 2 minutes in at any one time. But aside from the theme of a "governing body" being replaced by a new order, the series also share nothing in common.
What the year gap serves to do is make the game feel like you're playing Elder Scrolls V, not a gigantic expansion to Elder Scrolls IV. Environment alone, Skyrim (And just going off of speculation with that example) would probably be too similar to Cyrodiil; just take the forest and cover it with snow, and make more cities look like Bruma. If the rest of the world was still felt the same, then you aren't playing a new game, you're playing Elder Scrolls IV: Skyrim. Fable II changed the formula, that's why it deserves to be called "Fable II" and not "Fable: 500 years later...". Now, look at Fallout 3 and Fallout New Vegas. I played both of them. And while playing New Vegas last night, I had this same thought - Fallout New Vegas is the biggest expansion to a game I've ever played. I don't think it was ever the intention to make a new game in the first place, really. That's why it's called Fallout New Vegas and not Fallout 4. Things may be more brown than green now, and a few people speak in western accents, but it really feels like the same old wasteland. My character from the first game may as well have taken a long bus ride west and did the entire thing over again.
Now, take the things we know and love from Oblivion, like the Mage's Guild, the Empire, and then take the entire province of Morrowind, and just...*poof*, gone. It's no coincidence that these things changed the most. They want to specifically remove the things we are most familiar with. We saved Morrowind in Elder Scrolls III. We saved the Empire in Elder Scrolls IV...except not really, but you get the idea...They want to make things
new, and not just expand the things we already know. That's why Guild Wars II takes place so long after Guild Wars I, and why things are so different. Because change, for better or worse, makes the experience different. Stagnation kills series.
