Trinity Universe, though it has a linear story line, there is still plenty to do in it. Also though you are constantly hunting through dungeons it doesn't have the repetitive feel to it that most games get. If your hunting the Trophies it will take you a while to unlock them all and some of them are real annoying to obtain, for the hardcore trophy hunters this will be a breeze compared to most other hardcore games. Even though the stories are fairly linear, you still have optional characters to unlock, 3 possible endings, and you can play as either of 2 characters, which when you finish the game you can then choose to play as the other, keeping your equipment and choosing from 2 harder difficulties.
Not to mention the multiple references to other games and shows, there is enough comedy in the cinematics that removes the boring 2 minutes of conversations of events.
Due to these unique aspects of the game, this game will not suit everyone, though if you take the time to play it, you will most likely enjoy it enough to play through it at least 2 times.
