That doesn't count for Bethesda.
All that counts is sales.
Probably, but in the end, the RPG crowd is very selective and if you dont make new fans with follow-ups and disapoint the older fans, the franchise will eventualy die (for those who remember Lands of Lore franchise that died off due to a couple of extremely bad sequels that didnt apeal to the original fans)
Oh ... lands of lore 1, good times. Formidable game.
