This game looks a lot like golf. What I mean is that it's probably a lot more fun playing it than it is watching trailers of it.
I can agree with this.
So, are you also saying that creating a trailer for this game is not necessary or worth it?
I wouldn't say that. It's nice to see what the game is like. Also, you couldn't do a better job with showing your games with screenshots. I just don't know what to add or change in your trailer to better convey "fun".
