[quote name='emeraldgsl']To anyone who has played this game:
How good is it? and how many hours did it take to complete?[/QUOTE]
If you've played any of the earlier Prince of Persia games (Sands of Time, etc.), then you'll enjoy it. It reminded me of playing Sands of Time, though after a while the combat does get a little repetitive (but the same can be said for all of the games in the series).
I bought it for $19.99 at Best Buy when the first episode of GAMER came out (had a $20 off coupon for the game in it), and loved every second of it. If I recall correctly, it took me 10-12 hours to complete. However, I still haven't earned all of the achievements, so there's incentive for me to play through it again.
