I've quite enjoyed Witcher 3's atmosphere and story, but there's something hack-and-slash about the combat and the skill system that makes one not really want to explore the different skill paths. For example, almost everyone will deploy a large fraction of their points in strong and fast sword attacks -- because it's a hack and slash.
Is it there's not a lot of demand for RPGs, or they're too expensive to make, or the old-school creators are replaced with a younger generation?
Don't get me wrong, Witcher 3 and the late GTA series are great games, but they're not old school RPG's in their style of play: some of the missions are gauntlet runs (somewhat linear), and the energy is fast-paced and requires more reflexes than they require planning.
