My Channel is popping off, but I have some concerns

I make Roblox content, for context, a week ago a Roblox game I had been anticipating finally released, and I decided to take a shot at content creation, within 6 days my channel has grown to 1.8k subs and Ive finally hit 4k view hours to start running ads, heres the problem, I feel as though my entire channel is atop of this boat that is the game in which I make content on, and if this boat so happens to sink, the channel is cooked, but if I just start branching my Channel out and start making content on other games, I know I wont get nearly as many views + it would be a huge disservice to my subscribers, which might drive them away (I think).

Should I start another channel to make broader content? Or should I keep doing whats been working? Maybe its just too early to even bother with these questions? Please give me some of your input.
