The game requires at least 3 people to play with.
1. hit "Go" button and if you aren't logged in you'll go to login page
2. after logging in, come back out to main menu
3. hit "Go" again to start looking for match
(The number you see above "Go" button represents current online people, if it's below 3, the game won't be able to start)
Maybe I should add local single play with AIs.
