I can try to find you something more concrete online, so I'm just going from memory here. I was following it for at least several months prior to release, especially after Gameinformer did a gigantic and beautiful article about it. Through various interviews they were laying out all kinds of stuff that was going to be in it. Really impressive stuff, considering they had to beat Morrowind if PM's claim had any truth to it.
- Top of my head -
- Aging in game, with real time on the clock. So if you left your game on for a long time, or put enough time into it to equal a "long time" you'd physically age, from a starting young man on up.
- Building up stats like strength physically alters your muscle size. If you were to max it out, you'd have huge guns. This is a gradual build, not like what we've seen already.
- The more you use magic spells, the more you get those weird skin markings.
- Chopping down trees and leaving permanent stumps.
- Werewolves, and becoming one.
- If you're a bandit on the run, and you decide to live in the woods, you could develop certain allergies, and even get a skin tan from excessive outdoor exposure.
- Kill a shop owner, and take over his business.
- Real time vegetation growth, and you could do things like plant an acorn and watch it grow over the years.
- If you took your sweet time embarking on the actual main quest (like years and years) certain things were put into place to prompt you to hurry up. For example, if you had a wife and children (also possible), they might get kidnapped.
- Multiplayer options: any friend joining in will be an "alter ego" of your actual character. Anything they gain or find goes to you.
- Carrying scars from serious wounds.
That's all I can come up with, some of it might not seem like a big deal. And surprisingly I couldn't find much on Google about what was originally going into the game - most everything you find is just plain hype. And then Fable DLC started coming out. The claim was this DLC is what Fable was supposed to be! I'm not kidding.
Then Fable 2 was coming out, and they cried it's what Fable was supposed to be!
Not suprisingly, Fable 2 wasn't what Fable 2 was supposed to be! So I wouldn't expect much from Fable 3 - you're better off not knowing anything about it until you actually turn your game system on. That way you won't have to expect things to be in it. :shrug:
