[日本語がまだありません。書く暇が出来たら書きます。^^;] I dont know too much about the game but what I do know is that its set in the 0079 era but after a recent upgrade of the game system, many characters and mobile suits from other generations also appear in the game.
What you need to do is buy a starter pack - which consists of a few cards. The set of cards you buy will depend whether you want to be Renpou or Zeon.
Each card has a ton of information on it and you can see what one looks like here.
