The mobile gaming tie-in to Universal’s Fast & Furious 6 launched on the iTunes App Store last week and is #1 among free apps in 45 countries. Created with SF-based studio Kabam, it’s also the #1 overall game in 69 countries, the top racing game in 112 countries, and the #1 action game in 85 countries. Its iPad app version runs comparable if even wider in saturation as the top free app in 81 countries. By contrast, Paramount‘s Star Trek: The Game — tied to the release of Star Trek Into Darkness — stayed in-house and it’s doing lousy since it came out last month. According to VG Chartz, unit sales in its first three weeks are only 140K to date across PC, Xbox 360, and PS3 consoles. It’s also considered a failure because it’s very buggy despite years of development. Critics and users alike gave it poor reviews. So what happened?
