Out of curiosity, what do they see as flaws?, what's their self evaluation about their own game?
Honestly a lot of the same stuff you'd think.
Next game, companions are going to be limited to staff and cut down to 5 or 6 so they get more development. Also, there will be more actual interaction between companions - Savin mentioned he's already written some thoughts for fun interaction between his companion and some of the others planned.
Tobs mentioned that theres some things he doesn't like about how Kiyoko and Kinu were handled. Kiyoko wasnt originally going to be his companion - it was going to be a bird person or Garrett(!). I think he's planning to take another crack at a Princess-Maker type raising-type of character though.
Transformations will be less of a focus.
Savin has thought about making the next protagonist more defined, instead of a blob, to make them easier to find a voice for.
B will write yet another disabled furry!
What there *won't* be, however, is a more structured writing process - as far as I can tell Savin is of the opinion that letting people write what they want is the reason they put out as much content as they do.
Of course, all of these things are far off speculations. Not only is there a whole 'nother Act (so 2-4 more years), they'yll also do a big cleanup pass of a lot of stuff for 1.0 (so another 1-2 years imo).
