I picked this game up for $12.00 off Amazon last week.
I was looking for an action adventure game with some platforming, puzzle solving and third person combat. After beating Uncharted 1 and 2, I have been searching for something similar until the price drops on UC3.
Enslaved: Odyssey to the West is the closest thing to Uncharted I have found available on the Xbox. Enslaved is sorta a cross between Uncharted and Batman: AA. It has platforming which is very similar to Uncharted. The combat is more more similar to Batman games though as you don't really use guns (not so far in my playing anyway).
Anyway, I wanted to toss this title out there for anybody that really enjoyed the gameplay in Uncharted (platforming) and Batman (combat). So far the storyline is pretty interesting although not up to Uncharted standards but better than most games anyway.
For $12 new, I think it is worth the purchase.
