This new style of games have just started it and will potentielly grow in the next couple of years! The first episodic release was Bone (i think), followed by SIN and next Episode 1 for halflife! Next up we will have Sam and Max and Episode 2 for Halflife!

I think its a great way for smaller companies, like Tell tale, to release their adventure games, and also a great way for companies to keep titles alive while they create sequels! (as Bioware and Silicon Knights promised on Mass Effect and Too Human respectedly)

Now what worries me, is that when the smaller companies make episodes like this, and not enough buys into them! We wont get to see the end of the tales we are following.

Also the wait can be long, but ofcourse its longer when games like Halo 2 ends like it does, and takes it 2-3 years for the sequel release!
