First off to be honest I think the term Video game needs to change because it's evolved so much from entertainment purposes into an art of its own, but this is just a personal opinion. Now I think you will never get a "good" video game movie because the mediums of film and video games are so vastly different and to attempt to breed these to will either bastardize the game or make a catastrophically horrible film, there is evidence for both examples. Good films are about strong storytelling, relatively enjoyable characters (both the protagonists and antagonists), and real emotion (sadness, anger, exhilaration, humor, fear etc). Now although good video games fallow these rules as well they must pull on slightly different tabs. One of which being immersion of the player into the world of the game, we're talking sensory details, strong control schemes, and overall enjoyable game play.
On a personal note I enjoy a well crafted game over a film being as there is just so much more you can do in a video game then in a film. Think about sitting down for a ten, twenty, fifty hour film...you would just loose your shit half way through yeah. But a good solid game, you can easily loose track of time and clock in hours upon hours into a game. How many of us remember exploring every corner of a SNES game by the name of "Shadow Run" or "Super Mario RPG", or the N64 "Golden Eye" or "Legend of Zelda Ocarina of Time". And these are just our formative years I won't even begin with any of the Playstation's, Xbox's,Game Cube etc.
So what have we learned, well first off video games and films cannot exactly interbreed well for either art form. And that video games have evolved into a solid medium of art and social commentary, and in a least my opinion have the potential to be so much more then a film.
Now that I've wasted your time with my rant, I think a Far Cry 2 (This is crucial that the 2nd game be the base model) film would be pretty cool. MGS has to potential but would have to be done by a smart film maker and WELL crafted script. And I personally would think a BioShock film would make people piss themselves if done well.
