Add 170 to 70, then google "240 euros in dollars" - first hit: ZOMG is EA / Harmonix nuts asking for 370 frickin' dollars for Rockband? For comparison: the same bundle costs $150 in the U.S. - 97 Euros. So that's over twice as expensive.
You know? With most games, I wait a year or so till the price drops. Rock Band I was actually kind of excited about, to the point I asked Amazon to email me when I could order it. But maybe I will wait.
Note all the single star reviews on Amazon.
