we couldn't stay for long, so we just played one game

[theol]

I am writing a story about me and my friend wanted to go to play some games at the arcade after dinner. And then here is the following sentence:

“Since we both had a curfew, we couldn't stay for long, so we just played one game - the claw machine!”

I was wondering if “so” was a good conjunction to connect the two sentences.

Yes.

There's only one sentence there. You mean the different parts or clauses of that sentence.

You need an em-dash rather than a hyphen.

You need an em-dash rather than a hyphen.

Bear in mind that making an em-dash is quite difficult on a lot of keyboards. Many of us use an en-dash but with a space either side (as the OP did) to make it clear it's not a hyphen.

I do it too actually. I just realised. I think a better alternative is to use two hyphens (or two en-dashes?) without a space before or after.
