9. Fallout
Fallout is definitely a great series; it is one of those games that you can keep playing on and on and it will still be very enjoyable. It has good humor, a cool story, great characters, and a kick-ass enviroment. While these games can be turned into a movie (and I'm sure it would revive the genre of post-apocalyptic sci-fi), I believe a series can exploit the full potential of the franchise. If we focus on the main character's journey across the wasteland, on the people he encounters and the adventures he has, this can be a really great series. If the same writing team that has been working on the game in recent years works with the series as well, this can be a very long and enjoyable series.
