Nintendo is looking to cash in with their line of GameCube-enhanced-for-Wii games, Play on Wii. Of course, in the UK and North America it's called New Play Control!, as we've already reported. So how much will these games fetch?Well, Pikmin is set for a February 6th release, with Mario Power Tennis releasing on March 6th, and each title has a suggested price of £39.99, according to retailers. Nintendo has stepped in to say that their recommended price is £29.99, but it would seem that retailers aren't following that guideline. Should these games go for full price, even if they've got reworked controls taking advantage of the Wii's unique capabilities?
