If you aren't a Gundam Wing-nut, and don't know your Haro from your Tem Ray, here's the quatro uno uno on all things Gundam. In the near future, as Earth's population gets all billiony (10,000,000,000 to be exact,) the nations unite into the Earth Federation and start building a massive space colony. Hundreds of Diet Pepsi-shaped space colonies are launched into orbit. However, the colonies begin a struggle for leadership of the United Colonies Federation, which threatens to escalate into - you guessed it - war.
To avoid a big blow up, the Gundam Fight is proposed as a peaceful way of deciding which nation will rule the world. In the story of G Gundam, every colony has only one suit and it reflects each homeland. The colony that produces the winning Gundam then becomes leader of the colonies... at least until the next tournament. It's kind of like a Gundam Miss Universe pageant with the talent competition replaced by fighting ability.
On the action figure front, Bandai's new G Gundam models are a snap to assemble and tons o' fun to collect. And, if you ask me, they pose better than other action figures their size and most supermodels. So go on, collect all the G Gundam Models and give 'em a chance to rule the world. At least for a day.
