If you live in the UK, you may be able to get your hands on a copy of The Champion of the Wild before the global release date of November 2nd (when it will be available here on the website).
Those retailers are listed below. For the 2 lower stores you can place an order online on their website - click the links for Orc's Nest or here for Leisure Games. For the others, you'll need to just pop in if you're local.
If you are a retailer interested in ordering Champion of the Wild, there are only very limited retail stocks available but contact firstname.lastname@example.org to check whether there are any left.
