Elder Scrolls: Legends is receiving a relaunch courtesy of the folks at Bethesda later this year, and it's being ported to the Nintendo Switch, the Xbox One, and the Playstation 4.
This came in after the Rage 2 segment and trailer and was actually the first Elder Scrolls property they showed a trailer for, even though they had already mentioned Somerset.
Elder Scrolls: Legends is still available for download and free to play. They promise that your progress will be ported to whatever newer version of the game you play later this year.
They focused on the fact that the graphics will be improved. One would assume that they want this to be able to set itself apart from Hearthstone and the Eternal Card Game, the former of which has dominated the virtual card game scene and the latter being on the rise. There's also the Magic the Gathering: Arena thing that Wizards of the Coast is trying to get going, so this is a hotly contested niche right now.
In any case, I must profess my Elder Scrolls and card game love and wholly intend to try it out myself. For those interested in the trailer Bethesda showed at their E3 conference, we have it below for your viewing pleasure.
