That...isn't even a real game to begin with. Why would they remake a game that doesn't exist? If that's what you don't mean, why would they remake a game (''Mario Party 9'') that a lot of people disliked due to the major change in game mechanic? ''Super Mario Party'' does exist for that reason.
Ironically, Mario Party 3 was my first Mario Party game despite growing up during that timeline. I never played 1 and 2 until around the mid 2000s for 2 (via Wii Shop channel) and the early 2010s for 1 (after buying the physical copy from a retro game store).
