Haven't played Morrowind, but i'd have to say if i did, it could easily trump Fable.The Good/Evil system was pretty much flawed. You could just be a saint, buy all Light skills cheap, then turn evil by slaughtering a village and buy the dark skills.

Another good RPG: KOTOR. You actually have to think before you make a dumb decision. There are ways u can get killed by not even being in a fight. I recommend that if you haven't tried it out, buy the first one because it is less complicated and the low price won't make you regret you bought it if you don't like it. 

Haven't played JE yet, but I owned KOTOR and that was the friggin' best rpg i've played.  The Lightside/darkside is really balanced out and you have to actually think about what you are about to do, unlike Fable where you just randomly stab people. I almost cried when I listened to Mission's heartbreaking story about her brother, but it quickly turned to laughter when I Force Persuaded the wookiee to rip the little brat to shreds.

I heard this is real-time, but is it a weird hybrid style (kinda like KOTOR) or is it fully real-time?
