For 360. He told me this. I don't know anything about the main quest or any side quests, I asked him not to tell me.

He encountered a dragon really early on at level 3, playing a Melee character who uses a battleaxe and heavy armor the beast blew fire at him and was able to halve his health very easily, the creatures melee attacks once really wounded and crippled of flight still had a devastating close range melee attack and was able to surprising distance and close the gap between the two. He is playing on Default/Normal difficulty, so this is the game as it is intended at difficulty level from Bethesda.

Also the Dwemer Centurions pack a real wallop, as my friend put it "I walked into the Dwemer Ruin and this human like Dwemer robot thing cleaned my clock in about five hits."
