How about I play red dead redemption 2?
Sounds interesting. Why do you want to play red dead redemption 2?
I'm a huge fan of westerns and I've been enjoying them from when I was a child.
That sounds pretty cool!  I think you should spend your free time doing whatever you enjoy.  If that's playing a video game, then go for it!
I won't enjoy until you like the game too.
It is not up to me, you should enjoy it because you like those kinds of games. You can find other people who like it too so that you can share what you like with others.
