Several characters, all keepsakes, all fish except, I think, one, at least one background element…
The voice acting is all there
I’d be very surprised if the number of voiced characters isn’t significantly higher in the finished game. And, of course, we’re missing the top end of the relationship interactions with all characters, which will definitely be voice acted.
the mechanics are all there
I wouldn’t be surprised if we get some new mini games in certain parts of the map we can’t access yet.
Apart from these minor nitpickings, however, I completely agree (well, except that I haven’t had any crashes or significant bugs); I’m already enjoying the game as much as the first one, and I definitely feel I got my money’s worth, which is sadly quite unusual for too many supposedly complete games these days.
