Well, sounds cool. I hope with all the trophies in Melee, there might be "Trophy Matches" where you have to fight in Eagleland for other trophies. However, that's probably not going to happen.
Itoi didn't include many in Mother 2. That is true. However, MY ideas for some Mini-games would include these:
Mr. Saturn Hide: (Not to be confused with the Software)
If there are to be Mr. Saturns, (Which I think I remember hearing about) then I would want Itoi create this. One Mr. Saturn would be found in a city, let's say, "Porkandbean City." Upon finding him, he runs away and leaves an item. Then, he appears in Saturn Valley, perhaps in a empty cave. Then another one appears in another location. That way, you have to find them all and get all their items.
Itoi COULD use a fair-like setting similar to Chrono with small "Carny" games, but that isn't Earthboundy to me. How about, instead, having the version of the Runaway Five in Mother Three need help and you would have to get enough money from gambling in a casino. (Like, let us say, they need more attendees, and you need to each enter for the price of 100 casino credits 10 times to their show, each time, more people will come)They Itoi could include a Casino Earthbound Style. Can you say Fobby Roulette? Or maybe not.
