While 2015 was a very good year for RPGs, it was more a year for derivative RPGs than classical cRPGs:
The Witcher 3: Wild Hunt - No character choice, Single character
Pillars of Eternity - Classical RPG but with cruddy last third/quarter
Fallout 4 - de-emphasised direction, emphasis on distractions
Underrail - Single character
Age of Decadence - A choose your own adventure
Shadowrun: Hong Kong - not sure yet, haven't looked into it much
Legends of Eisenwald - tactical battles, RPG and strategy elements, none with overall dominance
Undertale - Just messes with everything as it's selling point
Serpent in the Staglands - Classical RPG but with weird spell system
Blackguards 2 - emphasis on tactical battles and cutscenes
I mean, there's something for everyone there, but for anyone who's only really interested in the core RPGs, such as Wizardry-likes or Balder's Gate-likes then its as much a barren year as 2013 and before and 2014 was indeed a better year (with Divinity: Original Sin, Wasteland 2 and Lords of Xulima all providing good solid >80% experiences.
And I would say there are 2 distinct types of classical experience because there's a distinct difference between a Dungeon Crawler and a predominantly over-world Heroic Epic Fantasy, though the two are equal in their claim to legitimacy, the core features being a customisable party of adventurers who loot and level via customisable paths while exploring someone's pre-made PNP-like module.
There have always been derivatives and derivatives can be extremely enjoyable games, just look at King's Bounty (early 1990s) and Diablo (mid-1990s), both of which gave birth to huge numbers of cash-ins and future classic games, but neither of which has ever really been classed as a 'proper' RPG even by knowledgeable fans.
Semantics are all fun and good for forum entertainment, but if you slap a Wizardry-like or a Baldur's Gate-like in-front of anyone here then they'll be like "oh cool, an RPG", but if you provide anything else then people will be like "ok, so what does this game do, what's it like?" (aside from the usual disinterest in very low budget/graphics games with virtually no hype), to which the first question is usually "Does it have respawns?" etc etc etc.
