Fable is a great game, and I think you played the Lost Chapters since you mentioned the Dragon boss. I beat both the original and Lost Chapters, and they wre great. But they were way to short and easy, and leveling up was no challenge which I hated. Not much variety, but straight-forward and simple; great for beginner RPG players. I showed my dad Oblivion, but he liked Fable more since Oblivion had way too much to do and took a long time to get successful.
The story like was great and intense, and was always on the move. But it was too short, and the expansion pack barely increased the duration. Also, the expansion added two new spells, two spells which did the exact same thing, but had different colors; only red and blue. The new weapons were pretty cool though, and the clothes and towns were definately needed, too.
I'm the kind of gamer that likes to work his way up with almost nothing and stay like that to have more of challenge for a while, and for the difficulty to increase as I increase, using the worst weapons for the longest time I can. (Yeah it's weird).
For my last paragraph, I want to complain about the legendary early quests. I created a new game, and what I did, I went to the cave of Hobbes and killed constantly until I reached legendary status. And when I did, I went to the Guild and looked at the Quest Cards, and the Knothole Glade Tax Riot quest was up, the only legendary quest left for me to get. So, I clicked on it once, and the map went black, and it wouldn't give me the quest. A dumb glitch that couldn't've been my Xbox acting up. It's almost impossible to get the Hook Coast Legendary quest, too.
