I don't think being new IP has any bearing on the success/failure of any of the games listed here. Most of them were simply rejected by the market for numerous other reasons.
If you bring something awesome, people will bite, new IP or not. I love new IP... just not these. There's a whole laundry list of issues I have with those games, from purely technical issues (Wild Hearts / Aveum / Forspoken) to art direction I strongly dislike (Aveum / Atlas Fallen / Lamplighter's League). There were always other new games I'd pick over these.
Shadow Gambit is the only game on that list that looks really good to me, the Steam demo was also great! I will admit that I didn't buy it though, because I'm swamped in games this year. When you're a second/third priority game you don't stand much of a chance in this onslaught of massive time demanding games, this goes for known IP as well, I've skipped my fair share this year.
Shadow Gambit is excellent, strong recommendation.
