Tribal Wars
Origin: InnoGames, © 2003 - 2012 InnoGames GmbH
Rundown: Tribal Wars is a browser-based multiplayer game. You are given a tiny medieval village and a few troops, and from those meager beginnings, you're meant to build a whole empire. As you build more troops, attack other players and use resources, your village gets bigger and bigger. You're ranked on how many enemies you kill, how many points you gain in building up your village, how good your defenses are, and how many villages you have conquered while building your empire. It's also a real-time game; if you want to build up an iron mine, then it takes maybe six hours for everything to be completed, so the game is rather slow paced.
My Rating: 10/10
This is by far my most favorite of the games on the site. I play multiple times every day, and I started playing last year. I have yet to get bored with it. I love the messaging system, the conquering rules, and the wars you can have with other players. It's a true strategy game and it keeps going for months and months at a time, so I really love it.
