When I heard the rumours of a Buffy movie I, like most fans, got caught up in all the excitement. Even though it's not happening as far as we know. But I actually think a new video game would be a far better idea.
Firstly, a movie if not done right has so many chances to go wrong and ruin people's memories of Buffy, but I don't see that danger in a game. If something you hate happens in a movie it's cannon, but video games aren't. So they go with a plot you dislike? not a problem it never happened.
Also, they can set it whenever they want. Your favourite character was killed off before the end? don't worry they're in the game.
I know they were planning to do a nintendo ds game (As I don't have a ds I haven't a clue if they did) but frankly I think having the last ever buffy video game on only one platform is a huge screw to the fans.
In the only buffy game I own (chaos bleeds) they got a good amount of the actors to do their voices. Anya, Willow and Buffy were the only ones who didn't but I'm sure they would now. Emma Caulfield and Alyson Hannigan didn't because of schedule conflicts, which if the game wasn't rushed would be easy to work around. SMG didn't because she said she only would if they sent her a script before she agreed and they didn't. Now I've heard gripes about Sarah in situations like this (like not doing extras) but I think she was being perfectly reasonable. Why should she agree to do something without seeing a script? So as long as they sent her one she might be on board. Even if they couldn't get them (which I think they could, at least a good few) the girl who did buffy for the game was good. the only problem was, she did a great buffy but her willow and anya sucked. Easily solved though. Either get 3 impressionists or get 1 who can do all 3.
Plus, look how far the graphics have come since chaos bleeds. I have included 1 pic of the chaos bleeds graphics and 1 of the new tomb raider's. A Buffy game would look awesome! (the tomb raider still I got isn't even a very good one, so it's even cooler looking!)
Finally, playing a buffy game would just rock (not the most intellectual of arguements, but still true)
