No, this is not a joke. Lair can be played on PSP through PS3's Remote Play functionality. As discovered by Dubbedinenglish on the PlayStation forums, this is quite possibly the first Blu-ray PS3 game to run successfully on the PSP. By reducing the visual quality and increasing the response time, the game is actually quite playable. In fact, because the game uses the PSP's analog stick instead of tilt controls, it actually controls better than the PS3 counterpart.
