I watched King of Fighters last night. I fell asleep halfway through - the story was good, the actors....not so good. Afterward we chatted about it and we said 'it must have been based off a video game or summin'. NOT GOOD.
Also, Prince of Persia was bloody good for a movie adaptation. I got into it, and it's also made me want to get into the games. I haven't watched Tekken yet, but I am planning to on our next trip down to the vid store.
As for one of Kyle Ward's works:

And usually the process of having a book/game churned into a movie means that the company purchasing the brand may produce a movie
based off of the series. That means they might only keep the names of the characters and get one or two people who actually resemble the characters. It also means they can do whatever they want with the characters, eg. change their history, their current circumstance, and exactly what they have to go through, with a few strings here or there still connected to the original series. Dante might have a sister called Vergina instead of a twin brother. His mother might still be alive and possibly be addicted to drugs. Dante might start killing demons because he's forced to defend himself, but it will be without his macho attitude, a real woe-is-me persona. Dante might actually have completely black hair in a Nero style and wear sunglasses all the time. It is like darkslayer13 said, it's like fanfic. You get to play with the characters and the concept of their world, keep a couple of key ingredients from the original series, and the rest is history.
Unless, of course, Capcom retains some of the movie rights to the extent where they can say, this is what goes, and this is what is unacceptable.
But considering it's a movie being made from a game, it's likely that the movie company will have the final decision on where to take it.
I'm hoping they cast Nicholas Cage as a Jester type of character. He'd be awesome. ^_^
