It seems boycotts and petitions are all the rage these days. The latest is occurring across the pond in the UK over the price of Call of Duty: Modern Warfare 2. No, they aren't angry over the edition with night vision goggles, that kind of investment is to be expected.
Activision has priced that game at £54.99 - translated into American Dollars that's almost $90! Like any successful boycott, the best way to make a dent is to vote with your wallet. Total Gaming Network is stating that 60% of its user base is boycotting the game. If the 60% number holds true it may make a dent.
For some perspective, most games are released for £39.99 to £49.99 in the UK. Though on Amazon.co.uk it's not uncommon to find games for £29.99.
