Finally someone who agrees with me! I wouldn't be influenced by reviews cause if I was, I wouldn't have gotten Riders and I never would have gotten as far as I am today. :P
I thought of a few random mini-games just to get the topic going I guess. :P
Here's one, I like to call...
-Each character must douse their plant (?) on fire by tapping the A Button repeatedly
-Dr. Eggman will write a sequence of buttons on the blackboard and players must repeat the sequence when called upon. Over time, he'll get trickier and faster. :P
Cool, huh? :P
-Guess what it'll be about. ;)
-1 VS 3
I would keep the card system in the game, I'd just include even more mini-games, more recent/unlockable characters, more stages to play on.... What else?
Would you keep the same Maginaryworld-like story? I certainly wouldn't!! I would suggest something along the lines of Dr. Eggman doing something that still involves cards and interactive boards... like maybe a new invention that takes them into a game where the only way Sonic and his friends get out is by winning the game... or something like that... but that's not the idea I have in mind, per se.
EDIT: Made ideas for mini-games. Maybe fill in descriptors later if there's interest:
King of the Castle
Stars in the Sky
Bomb Yourself (pun=Calm Yourself :P)
Three Blind Hedgehogs
Sonic Gliders (lol)
Repeat the Beat
Sonic or Tails
Rainy Day Stroll
Bustin' Out (Like Stop and Go... sorta..)
Hey, thought came to mind... imagine the possibilities if it came to Wii!
