How to salvage friendship between me (17M) and best friend (Also 17M)?

So me (17M) and my best friend (17M) have been friends since like third grade. Our friendship survived me and my family moving to CA for three years (we both did and now again both live in CO), but has crumbled because of, oddly enough, Breath of the Wild. My friend and I love playing video games together, but I had BOTW and he wanted to play it. No big deal, right? That's what I thought until he didn't even really talk to me the whole 2hr time I was at his house. He was too busy playing BOTW to talk to me. I was probably hurt a bit too much by this, and I being the person I am, didn't say anything, figuring it would blow over. It's been three months and we haven't talked but now he's invited me to watch Bohemian Rhapsody with him (over text) and I don't know how to respond. I want to be friends again, but am really, I don't know, nervous? I feel like I messed it up in the first place, and have no experience with this stuff. So, relationship advisers, What should I do to work things out and how should I do it?
