M-M-Mon-Monsters
Monsters Rule!
I was transported
to a faraway land
in a world where monsters rule.
I played the game like an Ace
Now I'm in this place
In a world where monsters rule.


I probly got the lyrics wrong but nostalgia

It's about training monsters and battling other monsters in arenas. To get some of the monsters, you can buy basic ones in the market, combine them, but for what the game is really known for, is pulling them off other random PS2 games. When you put in a PS2 game to get a monster from, it generates a monster for that disk and sticks with it. You can also combine monsters as well.

Ranching monsters.
