I didnt play in this game since 24 version. Is there any point to try current version. How much content has been added ?
At that point, perhaps since it's been a while, even if there isn't THAT much new content, maybe you'd consider it worth it, simply because some of it might feel a little new again? Perhaps try a different character build, like go full magic or something.
Don't forget to get a bunch of mods from the discord or that one Monster Girl Dreams wiki site, some of my favorites aren't working with the current version, but there's still some that are worth adding, so long as they suit your kinks/preferences.
Without spoiling:
You say version 24 is the last time you played, that's when they just added the labyrinth. Since then the labyrinth has essentially fully been completed and fleshed out, also patched up pretty well. I believe
more scenes like loss/victory scenes have been added to various characters including the labyrinth ones since then.
More notably, a
new location has been added, past the labyrinth. However, personally I don't like the new location or the characters very much at all. (that new location is pretty far from complete I believe).
But I'm picky, so if I were you?
Try it out.
Hope that was helpful, but I can't think of a good way to say, "how much content was added", without manually skimming each portion of the change-log.
