Examples listed here.

Children – They really add life to the game. The little brats just keep getting in the way.
Dragons – Every fight with them is awesome. I hate hunting these things down to unlock shouts.
No Attributes – I’m just good at everything! I have no idea what I’m good at.
No Classes – I can be anything! I have no idea what I am.
Companions – Companions are really helpful. My companions just die all the time, or kill me trying.

List some more.

Weapons dont degrade - Immortal weaponary. Far less immersive game.
Cant block while dual-wielding weapons - ????. Just not logical and is stupid.
Pizza - Tastes good. Adds fat.
