Howard makes a cutting board cleaner, oil, and butcher block conditioner. I use the latter every few months on our handmade boards and bowls and it keeps them well protected. The instructions on the bottle suffice for application.
If your pieces are particularly dry it might be a good idea to use the oil followed by the conditioner. I’m sure other mineral oil products would do a similar job but I’ve had good luck with this one and a bottle has lasted years.
It was an easy recent favorite of mine after a playthrough. The atmosphere is so well done. It got me to finally play Alan Wake and I’ll definitely pick up that sequel at some point too.
So, not much of a woodworker myself but it looks like the top is in three panels? You could use that as an opportunity for contrast as mentioned above and make the whole project look like it has some design intentionality.
Maybe a darker maple walnut veneer for that center panel as mentioned above and leather for the two smaller outer panels as mentioned elsewhere?
I have no idea what that trailer was about, so that tracks with FromSoft, and I love them for it, and I will be playing this. Probably after another base game playthrough
