One thing I'm a bit worried about with visualizing a video game that captures some of the Batman's greatest exploits is that it may come off as too easy if the cases were solved the same way they were in the comics, if the player has read them already. I suppose they could be padded, extended and altered significantly for the sake of providing a new story and a challenge. I'm not nearly as concerned with using old material for a movie as I am for a game, since you don't have as much of a personal stake in the movie as in an interactive story. Unless you're one of those pathetic drones who takes criticism of the movie personally, but that's another subject.
I would think that would be necessary for the Laughing Fish storyline if that were included in one of the games. One thing that's great about the Joker's threats is the suspense when the Batman is there to guard his intended targets. Anyone who's even so much as seen the animated series' version knows to look for the cat door in the second guy's home. Yeah, the cat could be too fast for the Batman or the game will force you to watch and wait with an FMV. Then again, the whole thing should probably be an FMV to at least pretend the player is surprised when it turns out Mr. Jackson is really the Batman and vice versa.
If I did the Laughing Fish story in a game, I'd probably want it to go along with some other stories that can be found in the TPB 'Strange Apparitions,' including Dr. Hugo Strange finding out whom the Batman is and trying to auction it off to the Batman's enemies, Councilman Rupert Thorn having Strange killed, and the ghost of Hugo Strange leaving a vapor analysis meter for the Batman to use to detect the chemical Strange sprayed the Joker with sometime earlier. What's that? Ghosts are too cheesy for the darker and serious tone Zaphod and I want in our movie franchise? Shut up. Ghosts in atmospheric video games kick ass and you know it. It's not like we're putting that in the movies or anything.
Anyway, a lot of the Batman's famous cases rested on specific, vital clues that could be used in the game as well, but if the player read those stories, they know exactly what to do instead of having to figure it out themselves. I think there's a way to add one or two big steps somewhere in there, so even though you're looking for what was in the comics, you may not find it until after figuring out a completely new inserted clue or lead. If that's the case, I'd put a warning in the game manual that says the stories have been altered for more challenging gameplay and that knowledge of the comic stories' cases alone won't be enough. That should save some time, in case the player spends hours looking for one thing when it isn't yet available or likely to be found. I do want the game as user friendly as possible, even if it's supposed to be very challenging.
The kind of detective work that would be in this game would truly be a first (as far as I know) and would resemble 'Law and Order' and other criminal justice shows in some ways in terms of how you're supposed to track people down. Of course, it's much different, since you don't have to follow the rules even as much as Lenny Briscoe chooses to when no one's looking. The second game needs to be more challenging, since you have more goodies at your disposal, both for tactical and investigative activities. The biggest factors I see right off as being big changes are the tracers and audio bugs. I've talked before about how those work. Someone either here or at the comic book store near my campus or both suggested that the Batcomputer filter the bug recordings according to certain keywords. There would be a lot of keywords, though. Crime words like "kill," "steal" and all of their many, many synonyms, "Batman," the names of every major criminal in the database, police related words, etc. would be included, and specific names of people would be added according to what cases you have open and who's involved in any way.
The other big upgrade you get in the second game, aside from the more verdsatile and comprehensive Batcomputer, is the new Batmobile. The new one is like the typical ones in the comics, cartoons and the Burton movies. It can drive itself, it's got ejector seats, it's built like a tank (but it doesn't look like one), and it has a Batcomputer console inside, rather than simply a GPS system like in the previous model.
Another upgrade is you can carry more gas capsules in your belt, because now they're smaller gel pellets instead of cannister grenades, which means less trips back to the car and Cave to restock. You'll also have a miniature computer with which you can hack and access your database, and several other advanced items to use. It would be so awesome...
