Lego: The Hobbit. It's out at retailers for PS4, PS3, and Vita, but if you'd prefer a download version it's also on the PlayStation Store.
That'll set you back $60 on PS4, $50 on PS3 and $30 on Vita, so if you're after the smaller of prices, King Oddball at $7 might pick your fancy. The physics-based puzzler has an Angry Birds flavor, except it has a floating rock head who chucks smaller rocks around with his bizarrely long tongue. Oh and he has a crown on his head. It's been out on Vita for a little while as well as iOS, Android, and a few other platforms, but this is its debut on PS4.
PS4 also has the new Director's Cut of Strike Suit Zero for $20, while the PS3 makes do with a Sonic Unleashed download for the same price. If you're after a more palatable vintage, Persona 4 is this week's PS2 Classic re-release, meaning you can get it on PS3 for $10.
Finally, Stealth Inc: A Clone in the Dark is the latest PS Plus freebie for subscribers, and Episode 3 of Telltale's The Wolf Among Us is available to PS3 owners, priced at $5.
