Hell, I rent about three or four games a year. There's no way I'm paying Gamefly $192 in that span of time when I can pay about $40.
Different users have different needs and advocating more choices for the consumer is hardly moronic. I want games my way.
I definitely think it got a bum deal. It does start out slowly, but I think the review makes a decent case that some sites just buried it because it's a Gears wannabe that dares to have a single-player campaign and a high difficulty level.
"How easily" doesn't mean I thought it would be easy. It's just a phrase used when the exact level of difficulty is unknown. I have a lot of respect for those who master a musical instrument. I hope the review didn't give a contrary impression.
