GAOTED. Try it out. You raise your monster from a set of different types, train them up, and compete in MULTIDIMENSIONAL turn based rock-paper-scissors combat.
Such a great game. You really feel like the monster you're fighting has a mind of its own. Some bosses are really hard to find out how to defeat, but that's the game.
It was clunky. It was full of game mechanics poorly explained. This game set the foundation for the series and if you played it back then, the atmosphere it created was incredible.
Controls kinda suck. It was like this close to being a great game. Interesting level design, but holy crap the water levels suck and the camera is god awful in some places.
Aside from the batshit stuff that happens in the game it's basically the Heavy Rain of the PS2 console. The narrative really makes you want to do all you can to help the characters succeed.
You can destroy terrain to create line of sight for your teammates. It's a fun tactical gameplay game. The game has a fast-forward button for the cutscenes. No really.
