This is less a review of Icewind Dale itself than it is a review of the port. The game, in brief, is a classic for good reason; its challenging, engaging, and infinitely replayable. If youve never played it, youre in for a treat. If you have played it already... Youre still in for a treat!
The ports of the two Baldurs Gate games were frankly problematic, and doubly so on iOS. They have improved with patches, but the initial releases were fiddly and imprecise to control by touch and were riddled with bugs. The Icewind Dale port, on the other hand, is nearly flawless. Overhaul have finally nailed the porting process, and I havent had a problem yet. Youll need glasses to play it on anything smaller than an iPhone 6, but even there its smooth. On the iPad, it sings.
Bottom line, buy this game. I cant wait for the previous two releases to be patched to this level of quality! [Edit: for what its worth, the Baldurs Gate ports are now equally polished. Do yourself a favor and pick them up as well!]
