That's it.

I couldn't figure it out on the UESP.

Only a few years I believe.

For some reason I'm thinking 20 years.

I'm almost completely positive that it was 5.

If you look on uesp.net or a few other places that have lore, it says that morrowind started around the 3rd Era, 427 and Oblivion started around the 3rd Era, 433.

No, that's more like the time between the start of Daggerfall and the start of Morrowind though (but Daggerfall is supposed to have taken 10 years so it's about 10 yeas from the Warp in the West to Morrowind). Morrowind starts in 3E 427. Oblivion started in 3E 433; so six years.

4 years

Morrowind + Expansions was from 3E 427-429

Oblivion began at 3E 433

Skyrim is actually 400 years after the Oblivion crisis.

4-6 years? St. Jiub must have grinded smithing before he went out and did his thing.

Ummm...no it's 200, hence why it says 4E 201 on your calender. When Martin died the year became 4E 1.

Don't double everything.

Well it was the same Emporer in both Morrowind and Oblivion, so they couldn't have been that far apart in years

It was the same Emperor in every game from Arena (the very first game) to Oblivion. That's why his death in the beginning of Oblivion shocked us old-timer Elder Scrolls fans.

My first was Daggerfall, but i didn't play it alot at the time, it was quite buggy and i never did the main quest, just alot of dungeon delving, Morrowind was the first time i took note of Uriel Septim

To be a bit more specific, a more relevant game-related timeline. Canon-wise, the most solid dates are for the ENDINGS of each game, and the beginnings are often uncertain, given that you could take years for any of the main quests.

• 3E 399 - events of Arena, or its ending.
  
• 3E 405 - Beginning of Daggerfall. Apparently it was considered that the game would take the player 12 in-game years.
  
• 3E 417 - End of Daggerfall, with the event known as the "Second Dragon Break," or "Warp in the West."
  
• 3E 427 - Events of Morrowind, and possibly Tribunal and Bloodmoon.
  
• 3E 433 - Events of Oblivion and Shivering Isles. Last year of the third era. Fourth era begins at the END of the year, not mid-year. (i.e, there's time between Martin's death and the first day of the fourth era)
  
• 4E 201 (=3E 634) - Events of Skyrim.

So you can role-play a single hero from Arena to Oblivion, I suppose. Timeline works.

That character would be a damn legend

You can have a single hero from Arena to Skyrim. Anyone powerful enough in magic can live 200+ years, vampires are immortal, and the Nerevarine has corprus so he/she won't ever age or get diseased.

The problem is, a single hero across all games is kind of a travesty to the lore.

Ya, the Hero of Kvatch is Sheogorath in Skyrim. You would be playing a retcon.

And you would have to wonder why he is almost constanly going to jail

Clearly because the player is a kleptomaniac.

However, it would raise some questions about why you have to constantly re-earn your skills, climb to the top of all the guilds, meddle with daedric princes, etc. all over again every game. That would put the PC in the same category as Link or Megaman, losing all their superpowers and having to start all over again from scratch.

Actually, maybe that's why they are in prison - you lose all your skills back down to basics in there. Maybe it's all a curse of Nocturnal thing - you lose the ability for anyone to recognize who you are, and what you did, and she steals away all your nifty stuff, and leaves you in prison for a solid year until your godmode powers are rusty again.

No, it's clearly stated that the characters of each game are NOT the same; they reference the previous games with each one, and generally describe how the hero was taken out of the picture:

After the events of Morrowind the Nerevarine left Tamriel for Akavir.

....to reappear as a dazed and disoriented "punk" in Oblivion who gets tossed into jail for trying to steal some food.....only to vanish into Oblivion in Sheogorath's realm....only to re-emerge 200 years later in Skyrim, again oblivious to who and what he or she was/is. That sounds like some sort of divine curse, or a tormented and insane god (perhaps the Sheo episode revealed or hinted at the character's REAL identity).

Yes, being Sheogorath, plus hit with a curse from Nocturnal for also being the Grey Fox, simply being too insane to understand your own past almost makes a form of sense.

Clearly, the Sheogorath you meet in Skyrim is just a projection of your own mind, as well, since you expected to see a Sheogorath there that wasn't also you.

Your own mounting power levels are also a figment of your imagination - it's just insane to expect to go from novice nobody's ever heard of to master of the arcane in just a couple game days! Likewise, why does the rest of the world seem to keep getting stronger as you do? Clearly, you were just underestimating your own strength in the beginning of the adventure, and overestimating it by the end.

I prefer having a family bloodline rather than trying to pretend it's the same character.
