Outer Wilds is a unique open world space exploration game with a dark twist. The game is set in a solar system (not our solar system, and the system is not randomly generated) that is completely to scale, meaning all of the planets are their real-life (or close) sizes. That means that when you liftoff from a planet, there's no warp sequence or anything, you're simply in space! You can go wherever you want and do whatever you want. You can crash into the moon, go on a spacewalk, or visit the watery core of the Giant's Deep. But there's a catch. You can die, and no matter what you do, you will die, because 20 minutes after you start the game, the sun that all the planets orbit will supernova, killing you. But that's fine, because the world is on a time loop. Just like the movie Groundhog Day, you start the same day over again, except that you remember the events of the previous loop, and all of the ones before that. The difference here is that the ship's computer remembers all of the planets you've been to previously also. Each time, you get a new chance to explore, document and possibly try to stop the sun from imploding. This game is a beautiful game with intuitive, original zero-gravity mechanics and an excellent sense of scale, and for that, you should download it free for your computer from here.
I was browsing IndieDB one day and a banner featuring Air Brawl came up. It looked cool, so I clicked it, and I'm glad I did. Air Brawl is a brand-new game whose development just started this spring. It's a plane-fighting game made on the Unity engine, and it is currently in pre-alpha development. The developer, Wilhem Nylund, has released a free-to-play demo on their IndieDB site, and the game looks promising. It's in third-person 3D view, and the game features 3 different planes to chose from with a variety of wacky weapons to equip on each, from homing missiles to a "Batapult." This game has online multiplayer that runs smoothly and is easy to connect to, making playing online very simple! (EDIT: I apologize for my earlier mistake of saying that this game was LAN only. The developer has informed me of my mistake.) This game is fast-paced,and it's a blast to play with friends, so this one is definitely worth a try! You can download the game here.
