As many many many pepole already have written everywhere on the stores (not only GOG) this game is the NEW masterpeice by Soren Johnson, leads designer of Civ IV. It's an incredibly deep game with a wealth of game systems that ALL fit and click incredibly well together. The team working behind this is AWESOME form Soren and Leyla down to everyone of them, and the game is just *showing* that, the level of polishing and completeness of the game is just WAY over nowadays market standard, and no other game in my experience has been followed this closely by the developers which really listen to the community, in the end this game is just awesome as the people who are (still) making it. I already sinked *1250* hours in the game since the early days of EA, any comment would be biased enuff to not matter beyond what I already wrote, gameplay will most probably off-put you if you come from the Civ series, and that's all for the better. The game has *new*, fresh ideas and is a blend of characters grand strategy and tactical gameplay with a very heavy narrative, which does NOT get in the way but instead enhances your experience. And you'll find one of the *best* AIs out there to challenge you, its extremely well refined....of course, not perfect, as that's utopia, but still a VERY VERY challenging game, you'll sink many hours to master it. Note on Multiplayer: OW has been developed with a very clear idea of it being playerd in multi, and (again) it shows. This game is so good that even when you eventually lose (either against AI or other fellow humans), you'll probably be like "now that was FUN, let's go at it AGAIN". 5 stars, no one less.
