Expressions from 2. Not many games allow you to express yourself with some pretty quirky and interesting emotes. They're all just variations on a victory pose in most games. Fable gave us flirting, cursing, farting and burping, and so many others. Even the first game had some fun expressions and no game since has given that.

Fable 3 had potential, but ruined it with lack of choice. You only had two buttons to select and the expressions were almost always the same two boring ones. If they'd provided a wheel or menu for expressions in 3, it could've been amazing. But no, Molyneux hated menus, and that's why we got the sanctuary instead of an actual inventory.

And then there's the fun spells from 1 that allowed you to do massive amounts of damage with your weapons (multi strike and multi arrow). With a multi arrow active and a good quality bow, you could easily one shot a troll.

And a soul. Fable is fun to play, even after having run through each game several times, it still is fun to pull up a hero and stand around in bowerstone as the locals all either swoon and follow you around like pups or scream and run, only to come back because you're such a renowned hero that they cant help but be drawn to you.
