It used to be if you went to
https://us-adventureshop.gamesplanet.comyou'd get something that looked like
***this site*** (web archive link)
Now you get forwarded to
http://us-games.nexway.com/home.htmlwhich appears to be another game-selling site.
It "looks" kind of like the Nexway site might have bought out AdventureShop, but maybe they just bought the expired domain in order to direct traffic to their own website. I can't find any information one way or the other.
I doubt they are honoring past purchases that were made from AdventureShop.
They've connected to AdventureShop site at least since last year, where Robert Gray reported being confused by it in
***this thread***.
