Why not start the new year by learning something new? Like, say, learning how to make a video game?
If that sounds overly ambitious -- like the type of resolution or goal people set for themselves that they're never, ever going to accomplish -- fear not. Anyone can make a video game. Even you. Yes, you! In fact, you should make a video game -- make something raw, something personal, something only you could make.
In order to do that, I highly recommend reading through Zoe Quinn's introductory guide to making video games, which you can find below. It's full of helpful resources and tips to help you get started on game development. Some of these tools are so easy to use, you could have a game in minutes.
Now go out there and make something awesome.
