I was doing some research to write this, and set off a game trailer. It stopped playing and started buffering at the black ESRB warning screen on the front. Right at that moment my younger son walked in to bother me, did a double-take and said, "Ooh, simulated gambling?" This says something I probably shouldn't know about his weekend, and our game of the week.
Telltale Games comes in with a second installment in their Poker Night series. This time, it's Brock Sampson, Claptrap, Ash, and Sam (of Sam & Max fame) bellied up to the felts, with GlaDOS dealing. To sweeten the deal they included a large collection of items for Team Fortress 2 and Borderlands 2 gear.
Dead Island Riptide (a sequel to last year's tropical zombie nightmare) deserves a mention. The first game's visceral take on the zombie genre came through from trailers to closing credits. Early word is this one is more of the same, for better and for worse.
If you're on the look for something a little quirky, Thomas Was Alone is an indie platformer/adventurer that's been around for a couple years but has made it's way to the PS3/vita (it's a cross-buy).
