I haven't been able to play yet, since they decided not to port it to the Mac, which is frustrating. It is available for iOS and since the Mac now uses the same chips and architecture as the iPhone, porting it to the Mac is just checking a box when compiling the code (I think; from what I've been told; but I'm not a developer so I don't know), but I suppose there are probably behind the scene politics to the decision. Oh well. If I decide to get the new iPad, I may try out D4.

To be honest, D3 was boring to me. 1 and 2 were moody and had a great story, but with part 3 they amped up the lore so much I couldn't follow it at all and the story became meaningless background to the skinner box mechanic: click click click, get so many "rare" and "legendary" items in just a few minutes to make the names meaningless, have a full inventory very quickly, forcing a return to town to sell everything. And repeat. No strategy at all, just click, upgrade, sell, about a few hundred times in each play session.

I shouldn't put it down—if you enjoyed it, that is great! But to me it was such a letdown after part 2. I hope for much better with part 4, whenever I'm finally able to play it.
