I remember the last time I was working for the US government during a shutdown. It was absolute chaos where I was at with people not knowing what was going to happen, or how they were going to stay afloat. I was on the military side of things so I wasn't really impacted.
I say grab a case of your preferred beverage, download any games you want during the steam sale, and pull all nighters nerding out in those games or SC until you're forced to go back to being a productive member of society :P
All jokes aside, I'm big on doing whatever gives you enjoyment in a healthy way. If you are looking for something outside of gaming, I really enjoy combat sports. Though it is a huge time and financial commitment depending on the facility. Some places are pretty standard (like $100/mo). Others are...insane. But the thing is, it's just as fun as gaming...and you sometimes get to kick someone's ass for basically free. It's great for your ego too. Nothing gets your mind right like getting your ass kicked by a dude half your size with tons more experience than you.
One bucket list item I want to do, is to take my PC to a movie theater and hook it up to the projector there and play Star Citizen on it. I know the response would be shitty and all. But just having the entire theater to myself and internet spaceships would be so awesome. Probably better to do that when it releases though.
Let's see what else...hiking is a good one. My fatass can barely make it up the tiny mountains where I'm at...we don't have bears or anything remotely dangerous so just be aware of what you have going on there. If you have any local ranges (guns, archery) that do live fire or night fire events, those are cool. Sometimes they have some of the big boy guns out there with tracers if you're into that kind of thing. Hunting of course is always fun, I only hunt to stock my freezer for a year or so. Usually one decent sized elk will do it. Tons of fun, similar to hiking if you do it "right" but just with a gun added to your loadout. Hockey games a pretty fun, a lot of times I think they are more fun than football. And I used to work for one of the college football teams currently in the playoffs (blasphemy on my part). If you have room to do any woodworking on the side, that can be fun as well as make you a shit ton of money if you're good enough. My cousin asks for my help on really big projects sometimes, he basically makes $5k a week easily. I mean it's a lot of work, and you have to know what you're doing. But there is at least something good to having those types of skills even just for your own home. Another thing you could do to pass the time is give me all of your expensive ships! Kidding. I ran out of ideas :P I'll shut up now.
