Pocket Legends, I maintain, is one of iOS' best technical achievements. It's a full-featured MMO, in the style of the legendary World of Warcraft, and it's available to play for free on Apple's App Store. It's huge among a certain audience (and, in fact, I've been told that audience is even bigger on the Android side of things), but I'm surprised that even more players haven't tried this game out to see what Spacetime Studios is working on.
Maybe this will help, though: to celebrate the game's one-year anniversary, Spacetime is opening up many of its normally premium content areas to all players for free. In a goofy video they made, developer Cinco Barnes says that all of the game's major premium areas will be open and playable to everyone until May 4.
If you haven't taken a look at this app yet, now's a great time to do so. Pocket Legends is free in a universal version, and it's definitely worth checking out.
