Nice to Sorare is exploring Hive !
I would say have a look at what Splinterlands is doing with the community and content creation here on Hive. They have quite a large stake in Hive Power as they need it to run the game and it's used to reward the community for creating regular content around the game and promoting it on other social media.
Weekly they have the Social Media Challenge (Link) which everyone can enter by creating an article about the game sharing it on other platforms (Twitter, Facebook, Instagram, Medium, YouTube, Publish0x, Tumblr, LinkedIn, Snapchat) Based on the effort that was put in these get curated by them.

There is also the weekly Battle Challenge( Link) where players can share a battle with a specific game rule which then gets curated.

On top of this, they have their own Community interface with splintertalk.io where all Splinterlands content is bundled and where players can earn the SPT token. Something like this can be created on hive-engine.com

In the end, it's mostly about the incentives. If Sorare had an account here with enough Hive Power owned or leased, it would be easy to make people join Sorare and create content around the game sharing it all over the internet to attract more players building a community in the process like Splinterlands has.
Hive is a Decentralized platform run by the community so there is not really such a thing as partnerships. However, it can perfectly be used to onboard and reward existing Sorare users by building a community with them here. It again comes down to having enough Hive Power as that allows to give upvotes which distribute their part of the inflation on the platform. Splinterlands (formerly steemmonsters) that way gives great incentives.

Basically, if you believe in Hive you can really make it work for you. If Sorare let's say was to buy 100k worth of Hive to kickstart things that would give roughly 250k HIVE POWER owned. This in total Daily at current price produces I would say roughly 100$ worth of upvotes (half of that you earn as curation rewards). This can be used to build a community and likely will become worth more during the bull market so it's an investment and not really a cost as it can be sold back at any time if it doesn't work out as hoped. I don't understand why not more companies/games use this as a tool especially at the current Hive price which offers a very nice risk/reward. It's a great way to advertise without actually losing the money that is put into it and likely even earning way more from it over time.
One of the issues I would say with the hive communities system is that users mostly use the ones that reward them the most. For example, I share my Sorare content in Sportstalk Community (sportstalksocial.com) as it's possible there to also earn SPORTS Tokens.
I hope this helps to get a better view on things, if you have more questions on the Hive Blockchain and ecosystem feel free to ask!
