Golvellius - The Valley of Doom has always been a firm favourite among our wise circle of Master System RPG gamers. It is after all a beautiful 8-bit action-RPG that I actually prefer over the original Zelda. What's more the thing has been made available on the iPhone, complete with Game Center support, a new UI, a variety of small enhancements and an almost perfect save system. You can get Golvellius at the App Store for less than 1$. Lucky you.
