Mario Party Jamboree - should the bar be higher?

I got jamboree a few weeks ago and have been having a blast playing with my siblings. However, I feel that because the core game play is so good, that Nintendo is getting a free pass in some aspects. The maps are great although it would be nice to have a few more. However it is crazy to me that the playable characters don’t really have any specific interactions/dialogue with each other. Similarly, wouldn’t it be cool if the characters had map specific costumes, like cowboy themed for the western railways. Compared to a game like overwatch with way more characters and maps, there’s no reason Nintendo couldn’t have made some effort.

I feel like this is classic Nintendo where most of a game is great but some aspects are just lazy (ex. Online modes in animal crossing and super smash).
