For the past year Lego has been releasing games on the iOS App Store. I've played a few of them and they have all been disappointing in comparison with the phenomenal console games Lego is known for. The iOS games are scaled down versions with fewer characters and levels. They are shadows of the games they portend to represent.
Enter LEGO Star Wars: The Complete Saga for iOS. I still remember getting the original console game for Christmas six years ago (for Nintendo Wii if you're curios). It was a great game. This new iOS version is not like the other Lego games for iOS. This version is a legitimate port of the full console game and it's fantastic. When I saw it was released I freaked out and when I started playing it I freaked out again. The game is really great on the iPad. You get Episode I for free and Episodes II-VI can be unlocked with various In-App purchase options (full game IAP unlock costs $15). I haven't yet purchased the full game but garunteed I will soon.
LEGO Star Wars: The Complete Saga for iOS is a full featured port of the console game. It's fantastic and you can try it for free. This is the top notch work I've come to expect from Lego and their partners.
