Nier is a good game, especially if you like JRPGs and appreciate an excellent soundtrack. And at $15, it's a great game. I picked it up at GameStop a couple weeks ago and have not regretted it at all.
Went ahead and snagged the Collector's Edition for PS3. Used $25 Amazon GC that I got for Christmas, which brought it down to $14.99 w/ free shipping.
...I enjoyed the first game and after watching my friend play this for a while yesterday I downloaded the demo and loved it.
