Riven, the sequel to Myst, has become the most busy game on the entire App Store. To be exact, the file is 1,01GB in size and also requires about 2GB of free space to install.
“Riven for iOS is a huge application. We have tried to optimize Riven and reduce its original size on DVD to just over a gig. Even at that size, it is one of the largest iOS applications we know of, so be patient, downloading and syncing with iPhone can take a long time, "say the game developers.
They also recommend downloading Riven on your PC or Mac and then syncing your iPhone, iPod Touch or iPad with your computer to transfer the file. And although downloading Riven through Wi-Fi is possible, "it may take a while", about 90 minutes indicate the developers.
