From what little I’ve played of the game itself, it seems to be a good port of a fantastic game. However, to necessitate an internet connection on launching the game, particularly on a device that is as portable as an iPad, is a bizarre decision. A significant proportion of iPads are Wi-fi only. If you wanted to play this to pass the time when you’re traveling, or out and about, you will be disappointed.
This port is a bit like having a car that only allows sport mode when it’s parked.
If you already have it on computer, skip this app, as it offers no real advantage, apart from being able to play it while reclining on on the couch.
