I'm not quite sure if I'm correct since I'm not in the gaming industry, but I don't think there would be many benefits in terms of SEO for having provider name in URL. There are a few reasons that I wouldn't add provider name in URL:
- Your URL will be much longer, Moz suggests to keep it within 75 words, including https://www.
- I'm guessing the more important keyword here is the game name, by having publisher name you're moving your important keyword further from the root domain
- It cost more time and effort to manage and create content for each provider page/content
- Provider name is a branded keyword, and it would be hard for you to outrank them in their brand name
- doesn't give much SEO value
When I search for "Battlefield 1", almost all the top results have "Battlefield 1" close to their root domain.

I think at the end it depends on what keyword you're trying to rank for and does having the publisher name helps.
