I used to love Utopia, you could vuild things like crops and factories on your island, and random damage would hit like hurricanes... you always had to outwit your opponent. Now, imagine a style of game not too far off from that, but with more players, and a bigger world! The Grid! It's an addicting little retro strategy multiplayer game you can play in your web browser. It has elements of Risk, like taking over the board/screen, one square at a time, but you can also build up stats like gold, cities, farms, wizards, and become an overlord and rule forever - or play as a villain, wreaking havoc from the skies!
