Does it have less levels than the Chrome version? I enjoyed the game on the Browser.
The Chrome version contains one episode, and one one bonus Chrome exclusive episode. That's 63+7, a total of 70 levels.
The Windows Phone 7 version of Angry Birds will be identical to the PSP Mini version in terms of levels. This will include four episodes, ending with "The Big Setup" totaling 195 levels, so well over a 100 more than the Chrome version. What makes this version unique however is the inclusion of Xbox Live Achievements
(20 Achievements for 200 points) The price tag will be the
absolute lowest price a regular priced Xbox Live phone game can be priced at:
$2.99 (and the equivalent minimum in your country). It will be out tomorrow, this was confirmed with the "Must Have Games" promotion. This is the last title of the promotion.
The real winner here I think is the iPhone owners of the game. 99 cents for the most supported/updated version of the game. This means the entire fifth episode "Ham Em High" which is 45 levels, and the newest episode "Mine and Dine" with just 15 levels currently but with more to come. That's 255 levels with more to come. There's also Angry Birds Seasons (99 cents with many many updates) and Angry Birds Rio (99 cents as well, with new levels unlocked monthly). All support the "Game Center Achievements" a seperate achievement system that copies the Xbox in just about every way.
I adore this game on iPhone but I'm buying it again on WP7 for the achievements. It will be fun going through the game again on my Surround
