No one wants to put the kind of budget the games would require, because they would never make the money back.
There is enough criticism for quite a few of the adventure games that came out this year from from Kickstarter campaigns for not living up to the quality of the originals.
Larry Reloaded is hit and miss.
GK 20th Anniversary is a fun game, but its not as good as the original. It didn't get the same budget even. It shows in lack of animation and polish, and the atmosphere isn't quite right.
Broken Sword 5 was pretty good, but it has a lot of its old time fans against it for being to simplified and 'linear'.
Started on Dreamfall chapters, the animation and presentation looks great. But its really too early to tell what the finished game will be like. People might find it to be too "Telltale-esque" in puzzle design and interface?
I haven't played the latest Tex Murphy, so I can't make a comment. I think its mostly liked by its fans?
Broken Age? I see a lot of people complaining about it.
Some people believe that Hero-U won't live up to the QFG games, and it arguably leaning towards a different genre or style in some ways.
Space Venture, well we don't know much about it at all yet.
