Your post is old, but I don't think anyone has responded to it yet.
The actual town events are pretty boring, yeah. In Trio of Towns there really wasn't much variation on them other than the theme. My favorite town festivals are from BtN and probably always will be, unless they shake things up with this new entry. The heart events in Trio of Towns were some of the best in the series, though. Each candidate had (IIRC) five prior to the dating stage, and then I think three after that. There was also a lot of continuity so it felt like you were actually in an ongoing relationship. The FoMT remake really glaringly lacked this, and I know part of it is because it was a remake, but it just made it obvious how bare bones the games used to be. I would anticipate PoOT (lmao) to be more in line with ToT than with SoSFoMT, especially since it's for the 25th anniversary of the series.
I'm still debating whether or not I'm gonna preorder. I know I'll wind up playing it eventually, and it's always fun to be part of the community when the game first comes out, but I'm still working my way through SoSFoMT and might be all farmed out by the time it comes out. The plush is really cute though and I am unfortunately a frivolous person
