You're welcome! It was a fun hyperfixation project. I ended up making the script so easy to use I decided to just scrape every other endpoint too, so if anyone wants it, here's a full dump of every endpoint, it's only like 4x bigger:

https://mega.nz/file/YF4F3bCS#pkS8Ki9QuucMGJF65YwGUE-NQZ78QEWs73fmF71qa18

And if anyone wants to do their own scraping to get more up to date data later, just pip install:

python-dotenv==1.2.2
Requests==2.34.2
tqdm==4.67.1

Put API keys in .env or export env vars:

CLIENT_ID=<client_id>
# Provide to fetch new token
CLIENT_SECRET=<client_secret>
# Optional, provide to reuse existing access token, secret will not be used
ACCESS_TOKEN=<access_token>

And just run python dump.py games or any other endpoint in the api docs like release_dates etc. It outputs the json and a simple log to an output folder wherever you ran it. No error handling or checkpointing so if it fails partway through you don't get anything, but I didn't have a single error the whole time.

usage: dump.py [-h] api_route

IGDB Dump Script

positional arguments:
  api_route   The API route to scrape, eg: games or game_time_to_beats

options:
  -h, --help  show this help message and exit
