Make Portable PC Games?

IS it possible to create PC Games as portable folders, the same way that portable applications appear? I guess it should be, but it concerns me since they usually contain lots of files and sizes of 2-3GB and more?
Answer #1
It’s not very mainstream, not at least for full blown games AFAIK.
Try searching the word “portable” in the games section. I would post the link I got of search results but I think the link will expire…
Answer #2
Yes..You can install and crack the game..Can be playable on other computers if you copy the game folder..
Some games need the registry entry…
