Its real this time. After a 10 month wait, a number of aborted release dates and lots of forum moaning Psychonauts has finally been released in the UK.
You can buy it online at Play, Game, or Amazon and Huz reports that Gamestation have the Xbox and PS2 versions in store right now, priced at ?30.00.
Update: The game is also apparently available in Norway. This review gave it a 6/6.
