... The League Of Extraordinary Gentlemen was made into a movie. Sucking all the fun out of its premise, the movie attempted to introduce famous characters, give them backstory, and lay out a logical explanation for why they're working together. If you've ever watched Van Helsing and wondered to yourself, "What would this be like if I died during it?" The League Of Extraordinary Gentlemen would be the hell that you'd go to.
Some movies are called "breathless roller coaster rides," and League certainly is breathless, but only because it seems like you're having plot points quickly and clumsily yelled at you from someone riding on a roller coaster. "THERE'S AN OLD GUY. HE'S IMPORTANT. GOT IT? AAAAAHHHHH. MR. HYDE IS AN APE THING, GOT IT? AAAHHHHHHH. HERE'S A SHIP, GOT IT? AAAAAHHHHH. THIS IS TOM SAWYER. GOT IT? YOU READ BOOKS, RIGHT? AAAAAAAHHHHH. MORIARTY. GOT IT? CREDITS. BYE." When you're trying to combine a roaring action movie with 200 years' worth of literature history, there is a clash of interests.

I'm using the word "interests" in the absolute broadest sense of the word.
Why It Would Make A Great Video Game:
Marvel: Ultimate Alliance is an action game with RPG elements. You can choose from a variety of Marvel heroes and use them to beat up whatever robots and foot soldiers Doctor Doom throws your way. The game also assumes that you know who Captain America is, so it doesn't give you any convoluted monologues or weird backstory flashbacks. The people behind Marvel: Ultimate Alliance knew that devoting 10 minutes to a "Before I was Spider-Man, I was a 90-pound geek and the only person that didn't punch me was my uncle" explanation was a waste of time. Any second not spent making robot widows was a second that didn't really matter.
