Dwarf Fortress Remote for iOS being on sale, together with the new simplified server installation procedure is a great opportunity to start playing Dwarf Fortress, even if you're spending this holiday season away from a computer.
It's actually fantastic. I was skeptical. No lag, the interface is excellent, and with a few very minor exceptions, it's capable of everything that the full PC game is. In fact, the games are transferable between the two. You can play a game on your PC, and then pick the same game up and play it later on your iPad.
If you enjoy playing Dwarf Fortress, whether via Remote or not, consider supporting Bay 12 Games - Dwarf Fortress authors who rely solely on players' donations for all these years.
