Biggest crossover game of all-time

While rummaging through some of my old sketchbooks, I found a bizarre game idea I had made years ago. it was untitled, and it featured an early version of Slam Wallaby (before he became a duo with Kasey Kockroach) and my other two characters, Ralph and Nelson.
Slam Wallaby's home is destroyed by Fartless, and he finds himself in a large metropolis. His quest begins to find his family (particulary his mentally challened older brother).
Meanwhile, Ralph the fly (the court jester) finds that Prince Kasey has gone missing. He and royal knight, Nelson the catterpillar are sent by King Donut-Head (who literally has a donut-head) to find him. Slam, Ralph, and Nelson soon bump into each other, and the three decide to join each other on their quests to find their friend(s). Meanwhile, the Fartless leader, Lord Demonor, tries to find King Kasey as well so he can kill him, so nobody would stop him from taking over the universe.
Each level was basicially a TV show, or a video game, with 3-4 exceptions. The levels are (in order).
Coocoonut Isle (Slam's home)
Midnight Metropolis (Here, Ralph and Nelson join party for the rest of the game)

lol, spongebob & south park in the same game would be awesome :p
I skipped a few lines of levels <_<

 

That... is one... freakin'... long game...

I mean... It's possible... If you want to make a 2D style game with something like RPGMaker. ^^;;;

...That'd still take forever to make... ._.

 

Yep. 36 lvls, over 50 bosses. :D
Anyone wanna try and help make this? XD

 

[cough] Minor programming, script/dialouge editing and some storyboarding here if you want me to help... ;P

Mostly script/dialouge is my field of expertise here.

 

Just recruit as many as you can. We need money, too. >>

 

kyu? okane/money? Why? [stares at Sevvi oddly]

 

For graphics and stuff. :P

 

I could handle the writing...

 

....hui? What insane person thought that Graphics = Moneh?

[koff] Couldn't we make them ourselves? [stares at Photoshop]

More writers! Sevvi! Write dat main script naoo!! Move it! [dumps collection of sharp pencils and notebooks on Sevvi]

[takes out highlighter and orange pen] Nao nao nao! X3

 

I might have time right time right now. >>
School stuff.
That, and we need ALOT more ppl than that. xD

 

Wait, who is the boss in Sly Cooper world?? Clockwerk?

And I can't write anything right now as I just finished one thing for school, and that's enough for today.

 

I could design the....backgrounds and weapons and what-not...you know...simple stuff?


GIMP can do wonders from what I've heard ;p​

 

Actually, it's an optional world found in Kockroach Kingdom. You can only access more and more 'missions' in that world by collecting memory cards throughout the game (like Hundred Acre Wood in KH).
Also, the boss at the end (after collecting all memory cards) is Raleigh, and just when Slam's game is about to go on, his PS2 shuts off, giving him an item for his efforts.

 

Okay. And, I use GIMP and it really does wonders.
