Point is - 18titans is a boring uninspired game based on a horrible IP with hideous characters. I think they've already acknowledged that the game was just a minor side project, and doesn't seem to be going anywhere.
FET is done, none of the tacked-on epilogue bonus scenes will improve the actual shortcomings of the game. These are mainly how inconsistent the books are, like the first steps in book 1 (which was more of a poor clone of Akabur's classic trainer games), weird book 2, slowly getting better in 3, while only book 4 is actually well made.
And we know the older books won't be improved to the book 4 quality, because that would mean fully redoing most of the game content.
So all the time spent on fiddling around with the finished FET and the boring 18titans would be better invested in a fresh game. Which - AFAIK - is already in the planning? Or is that off the table by now?
The knowledge how to make a game is there, art skill as well, but apparently not the grit to actually get the ball rolling.
