Which PS3 version of The Walking Dead game should I buy?

looks like you're looking at the 5 episode game of "The Walking Dead" and "The Walking Dead" First person shooter, which hasn't gotten a release date yet (games like that always have the Dec. 31 release dates)

Your friend is most likely talking about the episodic games since that has gotten much love and hype from everybody.

So in short, get the $30 version that is released on Dec. 11th.

Both versions are made by Telltale games, Activison is the distributor. One version is just the game and the other (the $70 version) is the collector's addition. The collector's addition has the game, a special box and The Walking Dead Compendium 1, which features exclusive Charlie Adlard cover art.and has over 1,000 pages detailing the first 48 issues of Robert Kirkman's award-winning comic book series.

The collector's addition needs to be pre-ordered.

Just buy the Walking Dead episodic collection when it comes out. It's distributed by Activision, I believe.
