Please give this a chance. You won’t regret it.

After waiting for years to get to play this game after it’s release, Ferel Interactive finally answers my prayers and delivers one of the greatest strategy games of all time. I did keep in mind of the warnings that the other reviewers gave regarding the dithering pace of the download time and the constant crashes that plagued the game. I want to assure all of you that the software update has not only fixed the major crash issues (I did experience only one crash after purchasing it, but nothing major), but online multiplayer has been included. If your mac has the latest update included (either Yosemite or El Capitan), it should only take between 2 to 3 hours to download, and afterwards it should be able to run smoothly. But please, be patient while the application downloads, and don’t pause it unless you’ve got between 2 to 3 hours to spare. I beseech this advice, out of experience, to those who are purchasing this game for the first time.
As for the game itself, it depends on what type of mac you use. If you want to expereince the thrill of a mega, epic-scale war (escpecially in multiplayer), then I advise you purchase a Mac computer that will sustain sharper graphics and large scale units. The game will play well on MacBook Pros and the latest laptops too, but it runs a bit slow. Nevertheless, after hours of battling English Knights and Saracens, I’d say that the updated version is worth the admission.
