Virtual Villagers is back, and we're so excited we couldn't wait until the weekend to tell you! With Virtual Villagers 3: The Secret City, the surprisingly addictive real-time simulation game sticks with its proven formula and makes a few minor tweaks to freshen up gameplay. With new secrets to uncover, new technologies, real-time weather effects and a whole new island to explore, Virtual Villagers 3 has all the ingredients that made the first games so compelling, plus more.

Super Energy Apocalypse, 2nd place prize winner in our 5th game design competition, plays a bit like a tower defense game, in that most of the time is spent getting ready for the next wave, and the player is offered no control over the targeting of the enemies. Planning for the battle is the critical strategic element, rather than the battle itself. The zombies come out only at night, so use the daylight wisely!

Harvest: Massive Encounter is a survival-based real-time strategy game with several modes of play that lend a free-form tower defense feel to the experience. You play the humans defending an expanding plot of land against swarms (and I do mean swarms) of alien UFOs, mechanized bots and other baddies. It's an extremely frantic game that's usually more nerve-wrecking than brain-stretching.

The sequel to Sandlot's Virtual Villagers-esque hit sim Westward has finally arrived! Westward II: Heroes of the Frontier continues the old west drama with a whole new batch of improvements, including 3D visuals, new buildings to construct, more scenarios to complete, and a brand new sandbox mode. Keep your townspeople happy, fed, and busy gathering resources as you expand across the uncharted territory in search of the elusive Copperhead Gang.

As odd as it may sound, Skyrates is a game about human-like animals flying biplanes between floating continents. Think Star Fox meets The Kingdom of Zeal from Chrono Trigger. You're a young pilot out to make an impact by trading, performing missions, and fighting pirates. Here's the catch: flying between islands takes at least an hour of real-time. The game was designed by a group of then-CMU grad-students to explore sporadic play, something you check like e-mail a few times a day. The result is not only interesting, its good enough to thread its way into your life.

Tarnation is a clever real-time strategy game by Brad Merritt that bears some resemblance to a tower defense title. You control a garden with rows of seeds ready to sprout into flowers that will dash off and dispatch incoming bugs. The bugs are made of Tar, you see, and if they reach the stream in front of your flower bed, they start to gunk up the water. Merely defeating all the bugs is enough to pass, but real excellence comes by releasing only as many flowers as you need.

Harvest is an upcoming game by Oxeye Game Studio currently in open beta. It is survival-based game that combines elements from tower defense and other real time strategy games. Those familiar with either of these types of games should feel right at home.

Playing with blocks is a universal experience, being not only fun for all ages but also an essential tool in development. Students at the DigiPen Institute of Technology have taken that basic structure and created a marvelous strategy game that involves not only stacking blocks but, in a stroke that some would call brilliant but I call mandatory, knocking your opponent's structures down.

Taking a page out of the popular village management book, the downloadable Westward (Windows) drops casual strategy elements into the mix for a game that's both interesting and a bit different. Westward pushes you across the unexplored old west setting up towns and hunting for riches. There's a surprising amount of depth in this game, yet very little was sacrificed to keep it user-friendly.

Steam Brigade is an exciting side-scrolling, real-time strategy game that uses a steampunk style and theme. The game is gorgeous and the production values are superb; and not just the graphics. The music is well-done, the story is well-written (cut scenes are in verse, no less), and the game as a whole has the polished feel of a retail offering. The designers' dedication to their work is present in every element of the game.

Tribal Trouble is a downloadable real-time strategy game for Windows or Mac. Compared to most RTS games, Tribal Trouble is easy to learn and to pick-up and play, yet it still offers a deep strategy that takes time to master. The game has earned many words of praise, including being a finalist for an IGF award, a spot on Game Tunnel's Indie Games of the Year list, and some impressive sales and downloads statistics.

Virtual Villagers is a downloadable real-time simulation game developed by Last Day of Work, the creators of Fish Tycoon and a number of other casual sim games. Take charge of a village of crash survivors and help them carve out a living on a jungle island. Teach them to farm, help them research scientific advancements and expand their population. It's a remarkably addictive game that's easy to play but impossible to stay away from!

Master of Defense is a simple strategy game about defending your townspeople from the dangerous monsters that lurk just beyond the town gates, and these monsters wish to do them harm. The game is a simplified real-time strategy (RTS) game, and it is downloadable for Windows only.

Mudcraft is a real-time strategy game playable in any browser with the Shockwave plug-in. Mudpeople gather dirt and water to make more Mudpeople, and they build huts to protect themselves from the rain. If caught in the rain, they melt and must be revived with more dirt. Gather resources to complete the objectives for each level. Delightfully dirty.
