Largest game I show in iTunes is: Dracula: The Path of the Dragon - Part 3 525.5 MB I've got a couple of apps larger than that, but they're not games.
Just wait for Riven to come out that game will be well over a gig but at the moment Crimson Gem Saga is the biggest i think
Dracula Path of The Dragon HD is one game trunk in 3 igames: 749Mb + 597Mb + 937Mb = 2283Mb = 2.230Gb That's from far the biggest game of the App Store that I have, quite bigger than original iphone version.
I can't read Japanese, so I never got the game. In fact, it may be bigger than 1.2 gig after install. However, apps in the same genre Purely are unique in that gameplay is limited to making a choice every now and then. So while it's unlikely that it's a good game, it may be a great story. I'll check if there's a lite version and download it to see what takes up so much space. For now, my money's on voiceover.
