It's a game of some sort!
Spyro, Ratchet & Clank, and Resistance developer Insomniac Games has trademarked a videogame called Sunset Overdrive. According to the filing, this is for "Entertainment services, namely, providing an on-line computer game." That's the beginning and end of what we know.
The name sounds interesting enough and somehow brought my mind, almost immediately, to OutRun. I'm not quite sure why. Hamza said it made him think of Sunset Riders, which surely has nothing to do with whatever Insomniac is working on either, but I couldn't resist bringing it up.
