How would YOU monetize this video game list?

Long story short, I've got a video game related website where I write about the news, updates, events, etc, for a very popular video game. I've been building the list at around 100 subscribers a day, and they're opting in for weekly newsletters about the game.

The list is getting decenty big (just hit 5000), and my subs are very responsive (40%+ open rate, with around three quarters of people who open the email clicking a link to a news article on the website). The only thing is I haven't figured out how to monetize the list yet.

I've created a shopify store to sell hoodies, shirts, hats, etc, focused on the game, but other than that, I'm stumped. I've been thinking about info products like guides, but it's really not the kind of game where you'd ever need a guide.

I've also looked for affiliate/CPA offers that my list might be interested in, but so far haven't found anything good.

So my question to all of you masterminds in the email marketing world; how would YOU monetize this list?
