Money[edit]
Xenosaga differs from most console RPGs in that defeating enemies rarely yields much money. There are a handful of creatures around the Xenosaga world that drop money, but the vast majority is earned through other mechanisms. Throughout the game, money is earned by investing in companies through e-mail, or by successfully completing a long side-quest to track down a hacker. Some money is earned from bosses, and a little bit is available from selling "Barter Items", such as "Scrap Iron". However, you can't get much money this way, and you can't do it very quickly.
Near the end of the game, a new AGWS unit is available for sale at the Dock Colony, for 300,000 G. This AGWS unit is extremely powerful, able to take out almost any enemy in the game all on its own. The AG-05 unit comes built in with 6,000 HP, and is capable of equipping the most powerful AGWS weapons available in the game. However, it can be quite difficult to earn enough money to pay for all of this. To earn money in the easiest, most efficient manner, make sure you understand the finer points of Poker.
