Roll your own version because you want to roll your own version, not to save 5 bucks.
It definitely won't fetch all the data that this person does though. It only fetches the current list of games on Steam, their store page information and some reviews for the game.
The code quality probably isn't amazing, but it might give you an idea of how to get started with your own scraper.
