Whilst I haven't worked on video games I have worked on plenty of software that is dynamic and powered from a database, mainly dynamic websites. You have a backend UI to add the data and they immediately appear in the frontend. You don't need to test every single thing you enter, the testing you did on the backend UI and related codebase does that. It really is very simple to add a new item or event or whatever it may be, it's basic data entry adding the parameters of the race. You have to double check you've entered everything correctly, but that hardly constitutes testing, and again, the backend is coded to make sure errors like 5000hp limit instead of 500hp isn't possible to enter.
Think about it, do we need to test every custom event we make? No, because they already made sure the event creation tool is functioning correctly. If we can do that, they can do it with their own backend tools.
Given their size it's not an unreasonable assumption that there is someone whose sole job, or one of a few jobs, is creating events. Again, it's not like there are only ten of them so one person is doing AI coding, adding events and car modelling. Everyone has their role.
Also, yet again, we know they have events they're holding back. It doesn't take a month to validate those events are working. They're keeping them back on purpose, to drip feed them.
Clues for what might be coming up in future updates to Gran Turismo 7 have come from a rather unexpected source: The Tonight Show Starring Jimmy Fallon. Current host Fallon was playing GT7 as part of a recent broadcast of the nightly talk show -- the longest-running talk show in the world, closin
