I really like the idea of board games playable on mobile devices over the internet where it doesn't matter how long each person takes to play their turn. Because it can be hard to organise a group of people to get together all at once to play a game, this way everyone is always playing, and the game just goes on, even if one person delays a bit. It will take a lot longer to play a game through, but who cares? The fun is still there, and you've got other games to play, too. This is just a way to play specific games with friends that would otherwise take a lot more effort and commitment to play.

PS - I wish there were more of them.
PPS - And that I could play them. Obviously.
