I need advice on unreleased game content

Hi guys so just like many people here, I am a newtubers. While my niche is gaming (yes heard a lot of problem with this niche)

The game im covering is not even released yet, its warframe spiritual successors from the same developer DIGITAL EXTREME called Soulframe.

Basically MMO Elden Ring just like Elden Ring Nightreign.

Im one of the lucky people to receive access code and we are approved to stream or make content around it.

While the community for soulframe is still smol, the subreddit only have aroun 18k ish redditor

I manage to get consistent 500 views on my shorts, and around 50ish views on long form.

I need the advice on this channel, should i keep building content library for now so when the game released i can be established content creator?

Or what can I do to grow the numbers from here even before the game is released?

Thanks before for all the kind advice
