Sonic 4: Episode I has been out on PS3, Xbox 360, Wii and iOS for quite some time, with versions for Windows Phone 7, Windows PC and iPad being released at later dates. Unfortunately Android users had been left in the lurch without the ability to play the title, but now it seems that SEGA has finally decided that those with Android devices should be able to play Sonic 4: Episode I, as they have released on the Android Marketplace for only $3.99/£2.56/€3.05.
This version of Sonic 4: Episode I seems to be aa mixed offering as it shares the same stages as the iOS version, which means the minecart level and 100,000 point pinball challenge are back, but it also includes the console version's overworld, though in a much more static variety. Curiously enough, the game also uses the graphical assets of the iPad version, which makes Sonic and the environments look more detailed. One little thing about this version of Sonic 4: Episode I is that it uses MP3's to play music. So yes, you can mod your own music into it, and if you want, give it a more classic Sonic feel. Imagine cruising through Splash Hill Zone with the music to Green Hill Zone playing in the background.
The odd thing though, is that the Android version of Sonic 4: Episode I, for some reason, requires permissions to have access to your phone number, which strikes us as a bit odd as there is no reason for it, and why a game of all things would need a phone number is beyond us. It also states that the game requires Android devices 4.0 and above to play, but
a few people have been running it just fine on 2.3.3, while others on 2.1 are running it fine, which just adds to the mystery.
