A better explaination can be found
here, so just read that. But basically, it is a grid-based game where you control a villiage that you can build up. When you set up your villiage, make sure to make it in the
NORTH-WEST since I will be around there. My name in MuShuPork]TL[, coordiantes (-159|97) so if your village pops up around mine, we can be allies! So just post your in-game name, coordinates, and your race if you want.
There's also a tutorial on the front page with an overview of the races and buildings. For the first 7 days, you cannot be attacked, so just worry about building up your economy first, and a Cranny on day 7 to protect your resources.
Cheers!
