What is the benefit of having different projects (console) than having a single project for all your different apps.
i.e
I have one project that is used for googlesheet auto update I have another project that is used for google email automation I have another project for scripting google Maps
vs a single project that is used for the sheet autoupdate, email automation and maps api.
Are the apps sharing quota limits?
The bigest thing in my opinion is the consent screen. When you request access from a user you are requesting access as an application
Now in this instance Google Oauth 2.0 playground would like permission to access my data. As a user i would assume then that only Google Oauth 2.0 playground would be accessing my data and not Super awesome other application under the same project.
Second issue will be quota. A number of the quotas are project based. So if you have a max of 50000 requests that the project can make and you have two different applications using with well. You are going to run out of quota twice as fast.
