What does によって mean here?

Here, によって means depending on or according to.

So:

• プレイ人数によって = depending on the number of players

This is a very common pattern:

• A によって B が変わる = B changes depending on A

In this sentence, the thing that causes variation is プレイ人数 and the thing that changes is セットアップ.

Why is it に よって and not just で or と?

によって is used to show that something varies based on some condition or factor.

So:

• プレイ人数によって、セットアップが変わる。 = The setup changes depending on the number of players.

If you used other particles, the nuance would change or sound unnatural here.

For example:

• で often marks a means, place, or cause
• と often marks a partner, quote, or condition

But によって is especially natural when talking about differences that arise from a factor:

• 人によって考え方が違う。 = Ways of thinking differ depending on the person.
