Instruct: Classify Amazon reviews into positive or negative sentiment
Query: I didn't know about the DRM

I read a good review of this game the other day and so placed it in my Amazon cart. It's a good thing that I tend to wait until I have several items before placing my order -- since putting it in my cart, I read Lifehacker's summary of the reviews of "Spore" on Amazon, so I came and read more of them myself. That was enough to convince me to remove it from my cart.
