I want this but in the true CAG fasion I'm going to wait till all episodes are released and buy them all at once when they offer them as a bundle pack for less on the 360.
Not trying to be mean but good luck getting a deal on the 360 version anytime soon. Telltale had to make a special agreement with MS to even get this on 360 since MS doesn't allow episodic content. The "main game" comes out for $5 tomorrow and each episode after that will be released as a game add-on for $5 each.
Only deal on it is $20 on PSN and you get a free Premium XMB w/purchase. Even PC people have to pay $25 for the entire series.
Like others I got this on PS3, which if you care, will be the easiest Platinum trophy in the history of PSN. All the trophies are just completing each chapter of the episode (all bronzes until the final chapter of the episode as a Silver, then a Gold for completing the episode, then a Platinum for completing all 5 episodes.) No special conditions or nothing.
I bet the max gamerscore you'll get on this game is a few hundred points. But we should be thankful it's even on 360, as 360 owners have missed out on Sam and Max and Back to the Future. Those worried about the last TellTale action point and click, Jurassic Park, don't be, they got this right.
Beware the demo is VERY short and is just one scene to get you used to the controls. If the download is the same size as on PS3, it's just under 500 MB.
As others have said, the teaser at the end of Episode 1 is awesome. I think the scenes slightly change depending on your choices (of which there are 5 major ones and a bunch of minor ones.) For those that get stuck, IGN Wiki's already has a guide up. On the PS3, at the end, it says how many players chose the same way as you. I'm assuming it's platform specific but not 100% sure.
