I played this on Xbox some years back, and though I am primarily a fan of shooters and RPG/shooters, this was a truly moving change of pace. It's still available for PC's for those who no longer have a working old Xbox. If you do, it's worth the rent.
I think its like one of those classic novels, that every literate gamer should give a try, though I know most will probably find it boring and tedious. But so are many 19th century novels. Worthwhile nonetheless.
