I would make a new Mario party this way:
Mario party 9 for WII. Characters and Boards
Default playable characters: Mario, Luigi, Peach, Yoshi, Wario, Daisy, Walluigi, Toad, Boo, Toadette, Birdo, Dry Bones, Blooper, Hammer Bro and Donkey Kong
Unlockable playable characters: Koopa Troopa, Diddy Kong and Dixie Kong
Boards, its hosts and way to get a star
Toadsworth-Toadsworth's vacation ship-classic way
Wiggler-Wiggler's gloomy garden-a star is on one space and costs 20 coins. You can buy how much you want if you have enough coins (just like in DK's stone statue for MPDS)
Shy Guy-Shy Guy's astro adventure-no star spaces. Each player starts with 5 stars. Use Chain Chomps to steal stars from other players.
Goomba-Goomba's risk casino-no star spaces. Win stars here buy playing and winning games of luck.
King Boo- King Boo's creepy corridors-you're in King Boo's haunted mansion maze. Search for him around the board and if you find him, he'll sell you a star for 10 coins(just like in MP8)
Penguin-Penguin's slippery lake-A long straight board. At the end penguin is waiting for you to sell a star for 20 coins.
Cranky Kong-Cranky's Kongo city-get stars buy giving money to hotel and becoming its owner. More money you give, more stars will you get.
E'Ggad-E'Ggad's wacky lab-There are three chests. Only one holds a star. You can check the chest for 10 coins.
Bowser-Bowser's wild volcano- Each player starts with 7 stars. No star spaces. Only keep away from Bowser who is roamin around the board or he'll steal a star from you(UNLOCKABLE).
