Are there any current RTS games that work on Mavericks that are similar to Age of Empires 2? I know AoE 3 will play ok, but I'm not really a fan. Also I have seen the browser-based Forge of Empires which is kinda cool, but they're just trying to sell you upgrades. Would also love to find something similar for iOS/iPad but I haven't found anything remotely similar. Looking for something that will consume hours of time, a technology-upgrade tree, good blend of offense and defense. I love AoE2, just looking for something similar to play while on vacation. Thanks for your help, Happy New Year!
