You're not wrong. But you're not exactly right either. Yes it seems to be a clift notes version of My New Family. Yes it seems like all the stuff happens in a matter of 3 weeks. Yes there is a lot of things happening completely without context, or any kind of actual character growth or progression. But once the weddings start happening, the story changes to be its own thing, mostly. And it isn't a bad one. Dev even calls out Killer7 in the credits for allowing what was used in game, including 2 cheeky renders of the family from MNF. I think this is fun from a "don't take this too seriously" standpoint and just seems like something to fap to. If you get the modded script that fixes the dialogue to be correct for the titles, it makes the time spent with it more fun. The visuals are pretty great, and there are a few original emotional scenes worth seeing. I am glad to be supporting it.
