What if Sega and Nintendo arn't as buddy-buddy as they appear to be since Sega's fall? I had this theory ever since Super Mario Galaxy came out.
What if before SMG, Sega had an idea for a game starring Ristar, a star who travel the depths of space seeking new planets and such, and had stretchy arms to defend himself and to travel.
If you noticed in Mario Galaxy, gravity isn't just a gameplay element but the use of propulsion, such as star launchers and blue stars which draws you closer. These forms of propulsion were present in the original 2D Ristar games only instead of gravity it uses Ristar's arms.
My guess that Miyomoto knew in advance of this Ristar game and either began work on Mario Galaxy or Nintendo asked Sega to back off the idea.
The only evidense I have to support this idea is this guy. He is the only evidence because his gameplays and control even his speed is ideal for Ristar. Don't just say "Hey, his arms are stretchy like Ristar", go and play the original Ristar game and compare Sonic the Werehog to him in basic movements like walking and jumping.
My second evidence is The Legend of Zelda: Twilight Princess. It was released before Sonic Unleashed but people still mocked Sonic saying Unleashed is Sega's answer for Twilight Princess.
Comparing his games as answers to Nintendo's game pisses me off.
If you checked the dates of the games, you'll find that Sonic Unleashed is in the middle of Mario Galaxy and Twilight Princess. Galaxy after Unleashed.
I know this is a weak theory but it is still a possible theory if you think about it. After all, we know Miyamoto is an alright guy, but what do we not know about him? (OK, silly question but you get what I mean)--Mystic Monkey sez 17:40, April 12, 2010 (UTC)
When it comes to gaming companies, each group is going to try to top one another, whether it be doing something the other company didn't, or doing things similar to what they've done. Of course Sega and Nintendo aren't buddy-buddy. It's all about money, and money is ultimately what's going to end their "partnership." -- Shelly the Hedgehog

Just what if Nintendo games are not as original as they are adored for and at the expense of Sega who Sonic is critisizing for ripping Wolf Link.--Mystic Monkey sez 10:27, April 13, 2010 (UTC)
