This is a joke, right?
£180 in the UK, but $169 in the US.
That's even £11 overpriced considering the traditional £1:$1 exchange rate that games companies seem to have always misguidedly used, but for it to supposedly come to retail at an expected 355 US Dollars (source xe.com) must be some sort of belated April Fool.
My take on it:
This is an argument for importing if ever there was one and if people living in PAL land haven't already bitten the bullet and done themselves a big favour.
The interminable wait for an official UK/Eur version while English language versions are already readily available in other countries is the main why I've imported to the UK since SNES days. The great thing about this generation and the last is that as the GB£ has increased in strength and the internet has increased in popularity, the days of £60+ imports have all but disappeared and bargain prices on new games can be regularly had, especially if you buy multiple games at once to save on postage.
This week I bought 4 Wii and 2 DS games (5 US and 1 Japan) and a Wii Nunchuk all together for £150 from an online store (not an auction website). All new and unopened. Going by game.co.uk the total recommended retail price for the 5 US games and accessory comes to £190. If you go into a shop in the UK, you will 90% of the time be paying the RRP because there aren't any independent games retailers worth visiting any more. The Japanese DS game is available at a local importer for £35 making £225 total. Why would you bother to pay more than 50% more for UK versions of games, after months of waiting for it to be translated into French, German, Finnish, Danish, etc and with the continued risk that console versions may not even support 60Hz mode in many cases? There's simply no point.
And so, releasing this game at that price is quite plainly an insult and gives no credit to anyone in the UK for being able to open their eyes, refuse to pay that much and simply not buy it. Sadly this has the knock-on effect that anything a bit outside the box at a high price gets low sales figures even in this large retail area, so in future anything a bit different doesn't get released in Europe. It's a vicious circle, but publishers are pricing themselves out of any future sales by releasing game sets at ridiculous prices such as this.
I'm sure you could buy the albums featuring the 9 extra songs for significantly less than US$186 too.
