I haven't finished this yet but tbh I find it kind of overrated. Like it's interesting and I like it and I'll defintely finish it but I definitely like it less than the Mario RPGs I've played.
As for Majora's Mask I had one go and it was interesting as well but I couldn't figure out what to do so I lost after about an hour when the three days had passed. It was really confusing with different people asking me to do different things that all seemed impossible like looking for something I couldn't find. That's the same kind of problem I had with Super Mario 64 at times: I don't like just continuously searching for things as a challenge, I want to know what I'm doing and for that to be interesting. I intend to have another go at some point but right now I'm doing other things in my gaming life.
I haven't played Mario Party 1 or 3 myself but they're apparently good so I'd buy them if it were me. But I have no N64
