I’m not usually into strategic war simulations – not at all, actually – but I can’t recommend Battle of the Bulge for iPad enough. It was recommended to me by a friend, and after playing through the free demo version, I pretty much immediately bought it (and it’s fairly pricey for an iOS game, at $10). The presentation is spectacularly done, and the gameplay is dead simple yet fun. My biggest challenge is in really understanding how to properly make my advances, without losing my supply lines – which basically leaves your advanced troops dead in the water. The game also supports online multiplayer, which I haven’t tried yet.
