Worth it unquestionably. It can be a really, REALLY challenging game, but quite rewarding. And even though it's a rail shooter, it actually has a TON of depth in its gameplay that is not immediately apparent (or may not be at all if you play it on easy).
What you should appreciate about the game (particularly starting with the second level) is that the game is immensely beautiful in its art design. Even though its a 1st gen Xbox game, it stands the test of time still because of the art.
Enjoy and you're welcome.
