Conquest game...in real life?
In My Kingdom, your goal is simple - build a kingdom by founding settlements, producing goods and conquering your neighbors. However, the component of this game that makes it very interesting and addictive is that the map is determined by your real-life location. That's right - your My Kingdom map is dependant on your GPS location in the real world. As you move in real life, your map moves with you. This allows you to build settlements in real-world locations - you can only build in areas you visit. For instance, I have one built near my home, another at my work, one by my local grocery store, near a gas station I visit regularly, etc.
Basically, no matter where you are, you can load up My Kingdom and it'll pop up a map for your location. Each time you load up a map for your area, it gives you 9 squares you can potentially build on. The center square is your current location, and then you have the 8 squares immediately adjacent to your location. Each square has unique resources (copper, rye, oak, fish, etc.) that produce in differing quantities (one square may yield 65% rye, while a neighboring square yields 87% rye).
This is where your settlements come into play. In order to harvest the resources, you have to build a settlement on it. From there, you can choose to build various buildings to initiate other actions - for instance, turning the raw resource in your square into a refined product (rye into rye bread, rye bread into rye beer, etc.), building defenses, etc. One thing to keep in mind is that you can't access a settlement unless you visit it in real life. In other words, say you have two settlements - one at home and one at work. If you're at work, you can't access your settlement at home - you have to be at the physical location where you built your settlement. So this means you want to build settlements in places you visit with some regularity - otherwise, you'll never be able to improve it unless you go out of your way to visit it. The one exception to this is collecting your goods - you can collect goods from a settlement without visiting it by sending a "Carrier" unit. This unit travels to your settlement for you, collects the goods, and brings them back to you - but it takes some time.
I won't go into all the details, but the crux of the game is that you build settlements in real world locations and then develop your settlements from there. You'll often run into NPC settlements along the way and may even chance upon settlements founded by other players. You can trade resources, fulfill "quests" and achivements, steal from opposing settlements, etc. There's plenty to do.
My major blow against this game is the user interface. It nearly turned me off from the get-go. Fortunately, I stuck with it and figured it out (and am still discovering new little nuggets each day). Basically, the developers could really accomplish some good by streamlining and improving the user interface. It's not very intuitive and a lot of the info is meaningless at first. You really have to dig into the game to figure out what's going on and what you can do - which isn't a great proposition for new players. You want to get them hooked quickly.
Like any game of this variety, there are a number of features that could be implemented to further improve it, but that's not a problem - games like this could always use additional features. However, improving the interface needs to be a top priority. It's attractive to look at, for sure. But it's a bit difficult to navigate and decipher at first.
In short, I recommend this game to anyone that's a fan of strategy, RPG or MMO type games. There's really quite a bit to do - it's just not all obvious at first. But trust me, it's there. The "real world location" thing is the bit that really got me hooked. Everywhere I go, I'm constantly loading up My Kingdom and exploring the map for my location. Running to the mall, waiting in the drive-thru at Burger King, etc. It's crazy addictive. My wife already hates it. :)
Give it a try. Very cool game with an extremely cool premise and quite a bit of neat stuff to do once you figure it out. If you're a bit underwhelmed at first, stick with it. It's fun and addictive. I give the general premise of the game a 10 - but I rate the game as a 9 overall, indicating the room for improvement.
