I would also have to agree that there are actually a lot more "proper/full rpg's", cRPG's, etc, that come out... then these ARPG and RPG-lite games.
I think the big difference though is that the ARPG/RPG-lites games get a lot more attention and a much larger marketing pushes, where loads of money is pumped into marketing so that people actually know about them. Where as the "proper rpg's", the cRPG's, etc, do not get a lot of money pumped into marketing (they can't afford it really)... usually due to that the companies which make them are often a lot smaller then the companies which makes ARPG's. Even CDPR is for the most part much larger then some of these cRPG making companies. CDPR has never had to go the route of Kickstarter to get their games made after all... and this is partly due to the fact that the Witcher games do basicly end up in the ARPG section of games, a section which does have a much larger player base.... which makes up another difference between these genres of games.
That difference being that a lot more people like to play ARPG's, then cRPG's. And many of these ARPG types of gamers tends to find "cRPG" way to complicated and/or boring (my brother being one of them... the only proper cRPG that he has ever liked playing was Dragon Age: Origins... but he is still in the firm opinion that Dragon Age 2 is THE best Dragon Age game ever made... an opinions which I do not agree with... DAO is to me the clear winner amongst the Dragon Age games).
Most people just do not have the patience, or will, or desire, to play anything more complex then Mass Effect or Skyrim, or the new Deus Ex games, or even the Witcher games... they don't want to have to think all to much, just mash a few buttons and kill some shit, get a bit of good story, and get to effect said story in some way... (where some of these games have better stories then others, like the Witcher games for example which tend to be in the top tier in that aspect). But once you start to addin more complex things, like actual character stats and skills and what not, which actually effects the game in some significant ways, like the old Baldurs Gate, or Neverwinter Nights, or the original two Fallout games, or Dragon Age: Origins, and all these new cRPG's, etc... then a lot of these players eyes start to glaze over, as they either start to become bored with these kinds of games, and even a few of them are actually mentally not capable of dealing with all of these stats and skills and what not.... because what they like is a lot more constant action based, where there are almost no downtimes to tamper with something like stats and skills etc.
Heck... that is still as true now as it was back in the "golden age" of cRPG's (mid 90's to about early 00's)... because as much as games like Baldurs Gate and Neverwinter Night might have sold, Diable (an ARPG) sold a lot more. Fallout 1 and 2's sales figures from back then are not really all that high in comparison either, not even today... I seem to recall reading gamingnews back in 2008 or 2009 or so, that Bethesdas Fallout 3 outsold ALL previous Fallout games combined in the first week of FO3's relese. Which compleatly comes down to that there are just way more people out there which are willing to play ARPG's, then cRPG's.
I personally prefer cRPG's over ARPG's... if I have a choice in the matter I would always want a game to be a full proper cRPG. But don't get me wrong here though... I still highly like ARPG's as well, and don't really think that cRPG's are superior to ARPG's at all, they are for the most part just different. And after all, on my top favorit games list, an ARPG game series places it's self higher then the highest cRPG game for me. It's just that game mechanicswise and statswise, and other such things, I tend to end up compleatly prefering cRPG types of mechanics and stats, etc. The reason for that is that I really like pen and paper rpg's, and any game which feels like I am playing an actual pen and paper rpg is instantly a win in my book. Fallout 1 and 2 where the first ever videogames I played which made me feel like I was playing a pen and paper rpg, and I have loved those kinds of videogames since then.
Games like Fallout 3-4, or the Elder Scrolls games (especially the last 2), or Deus Ex (especially the last 2), or even the Witcher series... to me they just don't feel like I am playing a pen and paper rpg... the closest thing I could compare them to in the roleplaying world, is things like LARPing... seeing as when you LARP parts of your own actual skill with it can matter a lot more... atleast a lot more then it ever would (or should) when it comes to pen and paper rpg's.
Anyway...
The list of new "proper/full cRPG" games which has come out in the last few years though has been larger then usual actually... thanks to the whole kickstarter thing, which showed that there are still a market out there with people wanting to play and buy cRPG's... a genre which basicly all big gaming companies, and/or (especially) the financiers and distribution companies, had for the most part abandoned some 10-15 years ago because they did not sell enough in their mind.
The list of new (or "new-ish") cRPG games that I can think of is below... and some of these has already been mentioned by others... but I will mention them again:
Divinity: Original Sin
Dragon Age: Origins
Legend of Grimrock
Legend of Grimrock II
Pillars of Eternity
Shadowrun: Returns
Shadowrun: Dragonfall
Shadowrun: Hong Kong
Torment: Tides of Numenaria
Tyranny
Wasteland 2
And currently there are also a few cRPG's being worked on right now, that I know of, that will come out soon or in a couple of years or so.
Divinity: Original Sin 2
Pillars of Eternity 2
Wasteland 3
There are probably more, and I probably know more of them (but have just temporarily forgoten about them)... but it is hard to keep track of them all... due to the sheer number of games (in general, not only cRPG's) that tend to come out every year. XD
I will say one thing though... the one genre which I feel has been highly underrepresented amongst cRPG's... is actually the Sci-Fi genre... especially the section of sci-fi that is not the post-apocalyptic kinds... you know the Bladerunner, Star Trek, Farscapes, Firefly, The Expanse, BattleTech/MechWarrior, Mass Effect, Cyberpunk 2020, etc, etc, etc, kinds of sci-fi. These kinds of Sci-Fi is extremely rare amongst cRPG's, which I think is a huge shame. Which is why I have been one of the vocal advokates on this forum for that I would want Cyberpunk 2077 to be much closer to a cRPG... where your characters stats and skills and what not are more importent then the players own skill in controlling a mouse and keyboard. Of course, considering CDPR's previous games, that does to a degree look unlikely, but at the same time some of the things CDPR has said over the last 4-5 years has to some degree indicated that we might just get a game which is a bit more stat and skill heavy compared to for example the Witcher. It's still uncertain though exactly what it will be... I will probably like it anyway, no matter what they make though... XD
