I saw this on Steam today, and I thought I'd mention it. I haven't played this particular version, but I'm very familiar with the board game, as well as the Ios version of the game. So this is not a review, just a general description of what it's all about. "Catan" is a computer version of the German board game of trade and building, "Die Siedler Von Catan", aka "Settlers of Catan". Players take turns trading goods, building roads, towns and cities, and playing cards, trying to gain the most points. The first player to achieve the point goal of the game wins. The game combines both luck and strategy as well as the human element of trading. The computer version does not include internet or hot-seat play, so that's kind of disappointing. I don't know how the computer version is, but the Ios AI was adequate -- not overwhelingly good, but fit my personal skill level (which is not astoundingly high either lol). Honestly, I liked the board game, but I was never a huge aficionado of the game (like some of my friends). I can say that playing the Ios game did improve my skills. The computer version also includes two of Catan's expansions: "Seafarers" and "Cities and Knights". "Seafarers" adds islands and sea lanes to the game to connect to those islands. "Cities and Knights" adds knights, city walls, a barbarian ship and commodities. The way I look at it, "Seafarers" doesn't fundamentally change the game as much as "Cities and Knights" does, which certainly takes it out of the realm of a simplicity and elegance. That doesn't mean that its a bad expansion, just that it makes it significantly more complex, as opposed to the Seafarers, which just gives you more strategic options. But keep in mind that the Ios version had a campaign which slowly added more of the complexity into the game. I don't know if the computer version includes that campaign, but if it does, you won't be overwhelmed by all the extra rules added by the expansions. BTW, I'm not buying the computer game because it has no multiplayer (I still have the Ios version, which suffices, and I feel no need to have it on the PC as well). But if you haven't played the game, or you lack opponents nowadays (like me) you may want to check it out.
