People claim Warhammer Underworlds: Online is a faithful adaptation of the tabletop game, I haven't played it personally, but it seems fun. At the same time, it's hard to give credit to the developer when the rules, cards and boards were designed by someone else. Also, the user interface is like what you would expect from a mobile game with a touch screen.
I'm afraid the game isn't free of technical problems either, performance is below what you would expect from a title that looks like this and it's prone to crashing. Don't even think about alt-tabbing on this one.
Finally, this game is multiplayer only and there are no players online. There's bots which is nice, but no singleplayer campaign or anything like that, all you get are so challenges. Given the circumstances, I can't really recommend this game.
