As said by Telltale Games on their site: 
 
 "Prepare for a different kind of poker night in a very different kind of club. In Poker Night at the Inventory, you'll deal with Penny Arcade's clever, cunning Tycho, Team Fortress 2's hulking Heavy, Homestar Runner's self-proclaimed "awesome icon" Strong Bad and the hyperkinetic "rabbity-thing" from Sam & Max. These characters come together in ways some never  thought possible, in a setting few would have predicted. You'll experience a new style of poker, particularly when hands don't go the way of the other fiery competitors at the table.  "   
 
Other info such as price listed here.More info should be released at PAX.

I'm not really a huge fan of poker, but maybe Telltale could change that ;)

My interest in this went form GET HYPE to what-fucking-ever in the course of a couple days.

Does it have online play? If it does I'll buy it.

The usage of a dialogue system could make this slightly interesting. The interactions between those characters could be interesting. And it's only $5. But I still want to see more before I decide if I'm buying it or not.

I don't know why everyone on the internet seems to be pissing their diapers because TellTale decided to do something cool with a bunch of really good characters for cheap. 
 

BAH! WHY ISN'T THIS AN ADVENTURE GAME!
