There is a difference to Wargames Vault purchases – each page has ‘Licensed to [name]. Email address: [purchase email address]’ at the bottom
(obviously substitute appropriate values)
TBH, I think this is a good difference
Wargame Vault has a similar thing. At the bottom left of every page, it has “[NAME] (order #[NUMBER])”. It’s optional, so only appears if the publisher has chosen to enable it.
