The devs aren’t putting any effort into marketing Rust right now. It hasn’t even gone on discounted sale on Steam once in the almost two years it’s been on there.
The game’s in alpha in Early Access. SHIT’S BROKE and this is not the time for worrying about marketing.
If you can’t handle alpha software, buy a game that’s actually released as a 1.0 with stability and optimization already sorted out and play that for a while until Rust is further along.
When Rust actually is polished up and is worthy of not being called alpha or beta anymore, then marketing’s really important, but right now getting millions more people to buy into Rust would just repeat the DayZ mistake: DayZ burned through its relevancy in alpha; even if they finish the game now, most people have already moved on. A large number of early Rust players have likewise moved on (for the time being, until it’s finished). Why would the devs want to attract tons of people now? Let the streamer see how bad the current state is and go “I don’t want to promote that, it’s not finished”. And then when it is finished, work on getting the word out (through advertising/marketing) that Rust isn’t a buggy alpha mess anymore and people should give it another look to see all of the changes. That’s when attracting streamers and their audiences really matters.
