I said it before and I'll say it again:
cRPGs aren't a genre of their own.
The only thing they have in common is additional layer of mechanics that's stuck onto a game belonging to another genre.
Stick it on an FPS and you get Deus Ex, TES or VTMB.
Stick it on an RTS with its base/unit production layer stripped and you have BG and so on.
Stick it on an action game with good melee combat and you get Dark Souls?
