you want to see a real idea.... it!

I have an idea where spyro,crash,and sonics worlds colliade and at first they fight at the temple ruins where gual attacked. They finally realize that they have a common goal.So they team up along there adventure they go to each others worlds and they get to know each other. In sonics world crash and spyro tease him about amy.In crashes world spyro drops sonic in the water.in spyros world crash and sonic meet cynder(like number 7.)and spyros kids.the bosses are: dr.cortex,dr.eggman,the dark master,and in the end a battle consisting of fighting all three at the same time in convexity.
