The PlayStation TV has, at long last, been released in Europe today. That makes it exactly a month after the US and Canada got it.
It costs £84.99 / €99.99 in stores (or you can order it online) and comes with 1GB of built-in storage. You also get a voucher for three digital games: Worms Revolution Extreme, Velocity Ultra, and OlliOlli.
PlayStation TV is a device that lets you stream PS Vita, PSP, and PS One classics to your television.
It doesn't work with all games available on Vita as you can see in the full list. And that includes all games that use the Vita's touchscreen.
You'll also need a DualShock 3 or DualShock 4 controller to be able to play the games once they're streamed to your TV. These controllers usually come with PS3s and PS4s, but can be bought separately too.
If you need it, there's a big FAQ provided by Sony right here that should answer any questions about the PlayStation TV you might have.
