I see reviews of people with 2nd gen and 8gb 3rd gen touches whining they got ripped off. This game REQUIRES a 256 or 512MB device. A 128mb device only has about 40mb free after os 4.2.1 loads. That is NOT enough to run more, modern, detailed apps/games.
Know ur device specs and read all fine print BEFORE you buy a game.
older, obsolete devices with (128mb ram - won't run a good number of high end games):
iPods 1 & 2nd gen
iPod 3rd gen 8gb*
*avoid this device at all costs unless you know you r buying a limited device. If u buy a 3rd gen iPod, get a 16gb or higher for best application compatability
Devices that meet requirements for this game - and most games/apps (256mb ram):
IPhone 3GS (2Xs CPU speed vs iPhone 3)
iPad 1st gen (A4 CPU)
iPod 3rd gen touches with 16gb or more storage
iPod 4th gens (has ret display, A4 CPU, but only 256mb ram)
Devices that exceed most any app requirements (512 or more MB ram):
iPhone 4 (512mb, iPad CPU speed)
iPad 2nd gen (512mb ram & and other cool features) - eta 2011
iPod 5th generations with 512mb
