I actually do have some stuff to say about that upcoming game. Mario & Sonic at the Olympic Games (AKA One of the longest titles for a olympics game) sounds like something nice for both Hardcore Sonic/Mario fans and new people to both franchises. I think the people who will have the most fun, are people that ae fans of both the Sonic games & the Mario games. Now i will say a few things based on the new screenshots and playable and/or possible characters.
1. Eggman & Bowser: i can see Eggman failing at most of the events (He isn't seen exercising much) and Bowser winning much of the Power type competitions and then losing on the speed type or racing (Unless he uses fire to burn the racers to ashes).
2. Mario/Sonic-Equal Amounts of characters?: Here is a small list on what the coordinating characters are in the game.
Sonic-Mario
Tails-Luigi
Knuckles-Yoshi(?)
Amy-Peach
Eggman-Bowser
With characters like that, what else will there be? Wario might return in the game since he is in alot of the Mario spinoffs. But if he comes, who coordinates with him on Sonic's side? I a VERY SCARED that might mean Shadow would be that one. I can't picture Shadow actually competing at something as family-friendly like the Olympics, he is just not that kind of character. I do want both Sonic & Mario to have equal amounts of characters, but i just hope Shadow would stay away from this.
3. Story Mode- I know that usually Mario spinoffs don't have that much of a story, but this is being developed by SEGA (Not Nintendo). Sega is more known to put stories in their spinoff games (Sonic Shuffle had a story, Knuckles Chaotix & Tails Adventure had a story). So could this mean this game will have a plot of some sort? I have a possible story includeing a possible ending. Here it goes: It all starts as a friendly meeting & then some just as friendly competition. But then i see Eggman & Bowser somehow working together to make sure THEY are considered the winners of the games. Which ends up in Sonic & Mario having to team up in events against Bowser's henchman & Eggman's robots. And a possible ending is that they defeat Eggman & Bowser in a final, last event. And as reward from the owner of the games, he gives BOTH Sonic & Mario a golden medal. Thus ending as friendly competitors, rather then fierce enemies. Go ahead and flame me if it sounds stupid, but if it includes a story and is rated E with all the innocent events going on PLUS Sega is developing it (Sega Spinoffs have Stories). This is a possibility.
4. Extra Eye-candy on the Screenshots- These are minor, but did anyone notice the crowd most notably behind Luigi? I can possibly point out both Piantas from Super Mario Sunshine and Chao from the Sonic Adventure series. If you can see better then i can on that, just reply and tell me that i'm making this stuff up. And also, who are the little creatures that are on some sign behind the Mario & Sonic dashing screenshot? Will they have something to do with the story? Or are they just random extras bored Sega artists did?
Hopefully, this will be a fun game. If Sonic is not in Brawl this will heal my pain a little (keyword: A little)\
