The App Store has been a haven for indie developers, allowing them to flourish with great original titles like Galcon, Spider: The Secret of Bryce Manor, and Above & Beyond Air Combat. But awesome titles such as these don't detract from the desire to play some of gaming's big franchises and classic series.
How could you not want to toy with a touch-enabled spin-off of Final Fantasy or shoot up terrorists in a Call of Duty adaptation? Franchises get big for a reason: they're fun to play.
While they may not have the cache of an indie title, it's hard to deny all the fun to be had with these ten mammoth series should they land on iPhone and iPod touch.
