Quick questions, i've had this game bookmarked for quite some time but never tried to dig deeper, so how close is this to being completed? Also how much content is there currently? Thanks
The game should be finished this year. The main story is already complete, so you shouldn't miss much by playing it now. The worst that could happen is if I expand one or two side-characters more, and they end up being featured in the ending (which you might be unable to see a second time unless you keep a save before going through the final section). Saves are compatible between updates (you just have to remember to copy/paste them before deleting the old folder), so there isn't much pain on that front either.
As for how much content there is, I have seen saves with 30-40 hours of gameplay time. It's hard for me to gauge it precisely, though, as I don't really play it as a regular player would. Also, if you are a completionist, there are some mutually exclusive paths/events, and I think you need at least 2 playthroughs to see everything (there is no "new game +", though).
