Good games yes, shit games no.
Skyrim is boring. It's a boring, soulless peice of fluff with far more dull moments than exciting ones. Almost nothing you find in terms of items, areas or people is worth the effort or remotely interesting most of the time.
Whereas The Witcher 2 is absolutely choca block full of depth and wonder. You simply have to replay it to discover it all.
Discovery is the main thing, and if there's nowt worth discovering then there's no reason to replay.
