Amazon has Crimson Seas for only $14.98 - this could be a possible pricing mistake as this game sells for $49.99 everywhere, so save $35 with this deal! Amazon is usually good with pricing mistakes in my personal experience - if they can't fulfill a price mistaken order, they usually hand out gift certificates, so it's worth a shot!
