DJ Hero will be $120 when it's released in the United States. Which is pricey, but not unheard of. When it's released in the UK, however, it'll follow a precedent set by Rock Band in being ridiculously expensive.
The title - which will bundle the game and a plastic turntable controller - has a recommended retail price of £108. Which in American Dollars is a whopping $177.
It's nothing new for British customers, but then, just because it's a regular occurrence, doesn't make it right.
