Through the Ages: A New Story of Civilization is currently the #2-rated game on Boardgamegeek – a ranking that tends to skew towards longer, more complex games – even higher than the original version, which is ranked #18, so it was perfect fodder for an app version, especially since the game requires a fair amount of accounting work to keep track of all of the resources and options. The app dropped last week for $9.99 for iOS devices and Android, and it is really stunning – great graphics, smooth gameplay, no glitches, and decent AI players – although I have to admit I’m not sure I love the game underneath it.

Through the Ages is essentially Sid Meier’s Civilization in card form, with a few tweaks. Players are competing to build tableaux of cards that represent growing civilizations from the stone age to the present day, playing cards that generate food, stone, knowledge, and happiness; making new workers by growing the population; adding new technologies; developing new military units and growing armies; raiding or declaring war on opponents; constructing Wonders, because every game of this theme has to have that; upgrading their government types; and probably six other things I’ve already forgotten.

On each turn, players get a fixed number of civil actions and military actions that allow them to take cards, grow the population, research technologies, or build buildings. The number of each is tied to the government type, with more advanced governments giving players more actions per turn. Everything in the game is dictated by the cards available on the rolling display; the first few cards cost one civil action to take, then the next group costs two, and the last three, with some penalties for certain card types. You’re really building a giant engine that will produce enough of the different resource types to allow you to rack up points in the end-game without creating unrest or running short of what you need to keep up with your opponents’ armies or feed your workers or lose resources to ‘corruption.’ There are substantial bonuses for finishing Wonders and in the Politics cards that will appear later in the game or at the end.

Through the Ages is incredibly layered, and requires more oversight, active management, and long-term planning than most games I’ve ever played. It has reached the point in some games where I thought, “Maybe I should write down what I’m doing so I remember what to do on my next turn,” which I think is a clear sign that a game has become work. I also had to monitor the AI players’ moves in the game log just to figure out why I was getting so thoroughly trounced (by the medium level, no less), and eventually pieced together a sort of rough strategy that involved getting Knights, Iron, Irrigation, and a couple of key military and science cards; it doesn’t work every time but I did finally beat the S.O.B. by doing that and ensuring I was never at a military strength disadvantage for the entire game.

The biggest bottleneck in the game is the need for an ‘idle worker’ to build or create anything new, whether it’s a building (farms, mines, labs, temples, and later versions of the same) or a military unit. You need a certain amount of food to grow your population, an amount that increases as the game goes on, and then those people need to eat, so you have to keep producing food to grow your population and build more things, or to destroy some of your weakest buildings to put those workers on more productive jobs. (Of course, they don’t actually earn any more for being more productive, as all benefits flow to you, which is one way in which Through the Ages reflects our modern economy.) There are yellow resource cards in the carousel that give you immediate, one-time bonuses of food, stone, or science, but taking one burns an action that you might need for something else.

And those actions are a second major bottleneck. Every player starts the game under Despotism, and can take a unique government card to upgrade to more modern systems that grant more actions – some give more civil actions but fewer military ones, some more military ones but not many more civil ones – and then burn either a whole turn or several rounds’ worth of science points for a “revolution” that changes your government type. You have to do this once to win, I think; I don’t know if doing it twice would pay off. But late in the game you’ll need more than the four civil actions per turn you get from Despotism.

Whereas in Civilization and other 4X (video) games, you can pretty much build whatever you want if you have the resources, Through the Ages dramatically limits your options because it’s card-based. There’s a ton of luck involved in the card draws, because the rolling market turns over quickly, with the leftmost three cards moving after every player if not selected; it’s easy to miss a card you need, especially those with just one or two copies in the deck. (All leader and wonder cards are unique, and you can’t take a wonder card if you have one currently in production.) The political cards aren’t quite a function of luck, but if you end up behind in military strength, your opponents can hammer you every turn, deepening your deficit by robbing you of population, resources, points, or buildings. Players play these cards into a LIFO queue, so playing one into it pushes the oldest one out, and many of those cards really stick it to whoever has the weakest army, more so as the game progresses.

Through the Ages never eliminates anyone, but deficits can grow exponentially, and it can be clear halfway through the game that you’re just not coming back. It also has one of my least favorite game features – players can have actions available without any way of using them. No one likes the frustration of having the right to make a move but not having the ability; some of this is a function of insufficient planning, but you can also just get stuck even if you did the right things earlier.

The app version is extremely well-done, with a tutorial that should be a model for other developers looking to port (or just create) complex boardgames to tablets. (There’s even a clever joke within it.) And the app has built-in reminders to cover numerous situations where you might forget a free action, fail to use all your actions, lose resources to corruption, or lose all production on your next turn due to an Uprising (in essence, if you don’t have enough happiness points to cover your population). There are so many cards with special functions that it’s easy to forget what you can do, and the attempt to render some depth to your civilization means wonders are in the way back, at least one of which, the Ocean Liner, gives you a new benefit each turn, fall out of sight and out of mind.

I found the light AI to be more of a training module, but the medium AI throttled me repeatedly before my first win. That doesn’t mean the medium AI is good, just better than I am as someone new to the game. It was instructive to watch the AI’s actions, and the game log, available by tapping a button on the upper left, is clear and useful. The game also has an easy undo function that lets you go back as far as your last irreversible move – such as something that involved revealing cards or a battle against an opponent. There’s a lot on the screen, but everything is brightly colored and clear, and once you get the hang of some of the images they’re using – like having a light on in a building to show that it’s occupied by a worker – they’re straightforward.

Through the Ages is above the level of game difficulty I prefer; it’s long and involved, requiring too much thought and planning to make it truly fun for me. I understand why players would love the game’s intellectual challenge and the reward of building something successful, but I prefer games that move a little faster and let me act more spontaneously. If playing a game with a beer in hand would make you demonstrably worse at it, it might not qualify as fun in my book. But if you like Through the Ages, or just generally like intricate games with long cycles, this app is just what you want.
