“Free-to-play” already has a nice ring to it, but when you mix it with “browser-based,” it sounds even better. The Settlers Online has both in it’s description. This new strategy game invites players to build a kingdom from the ground up — quite literally. You start with just one person and a few resources, and then build your empire one house at a time. The best part? The game is in open Beta, which means you can start playing right now.
