I am having two desktop systems at my home, both where running on Windows 7 and i usually use to play games on one of them. Few days ago, due to some official research work i required to remove W7 from both PCs and installed Snow Leopard and Linux on both PCs. Now as i heard about End of Nations (i love playing online strategy games) that is also a free game, i would like to experience it. But the problem is i dont have any Windows system as of now at my place. So i want to whether this game is going to be available for Linux or Mac OS Systems ? If yes, please let me know the system requirements as well.
