I have a game I'm trying to install using Parallels running Sierra because my HD does not have enough space to do it on my actual computer. So I d'led the game into the Guest OS and it runs fine in Parallels, but when I copy it to an external HD to play it from my actual computer, the storeassetd goes through and verifies the whole 50Gb file, but the game doesn't launch. I have actually d'led two large games this way and both act the same way. Games I have installed on my actual computer launch just fine from my external HD, so it appears there is a problem ( possibly computer authorization ) d'ling from the GuestOS. I did go into iTunes and authorized the GuestOS, but that didn't help.
This should be a limitation of Mac App Store distribution model: you may not be able to run application downloaded from other computer or virtual machine. Better to consult vendors of your games.
