Elder Scrolls Legends dropped on iPhone and Android recently and I installed it to try it out and it's a really solid port of the PC game. It seems Bethesda is following the tried and true path of releasing a digital card game on PC first, come to tablets next and then phones afterward. The phone ports come right in time for the Skyrim coming to Elder Scrolls Legends so if you wanted to try that out, now is the time.

Hopefully Valve and EA join the digital card game market and release phone game clients because by then we won't call them smartphones anymore, we'll call them card game handhelds.
