How to keep several games in one Unity project?

Question

Unity

Is it possible to support multiple games in one Unity project? They should have partially shared scripts responsible for the mechanics, but different graphics and build settings. Plugins are also partially shared, with different settings. Now this is solved by different branches in the git, but switching between them every time is very inconvenient. Is there any proper way to do this?

Answer 1

You create the necessary subdirectories in the project's dependency tree and make branches with dependencies: somewhere linking (links), somewhere copies of objects and unique objects only for this branch.
The main thing is that one such branch can be assembled into a game.

Answer 2

Git submodules. You can look in the direction of UPM, a rather convenient thing from units.
