I had this game about two years ago. To me it kinda seemed to be a mix of games in one.
You had some fairly free roaming and could proceed in the game at your own pace. What made it interesting was the photography aspect (for me) There were a number of weird and wonderful creatures in the game and you were awarded points for finding them. And of course there were a good number of rares to find. Very much like Pokémon Snap on the N64 in that way.
Other than that it was a fairly short, run of the mill adventure with below par combat mechanics.
Definately worth a play if you're bored though
