I definitely recommend Boards and Brews cafe in Manchester if you like board games. There's also a few board game stores around if you don't mind taking a day to adventure. Midgard in Derry is pretty nice, so is Relentless Dragon in Nashua. If you like video games and have an interest in vintage/older consoles, Core Gaming in Salem NH is awesome.

Manchester has some great bar hopping spots all along Elm Street. I'm partial to McGarvey's for a classic bar, the Shashkeen is a decent Irish pub close to all the downtown action and the theater nearby. I also like The Goat, they have a large whiskey selection and fun food, and live music every night at 9. Concord has some decent small spots too. Nothing too extravagant but good atmosphere. There's Penuches, which is a bit of a college dive bar but they tend to have good local bands on the weekends and decently priced drinks. I've met a lot of great folks there. Tandy's is a favorite for food, and I think they recently reopened their dance room in the back.

There's plenty of hiking and history spots up north, plus cute little towns with fun stores, great for day trips! I love the Cog Railway, and all the spots along Franconia Notch like the Flume and the Basin. Littleton and North Conway are some of my favorites for shopping, and they tend to have a lot of events going on in the warmer seasons.
