Every once in a while I'll come across free games for PC that look really good. Anyone can feel free to update this topic with limited time free game links so we can add them to our ever growing backlog of games. If a game states how long it will be free for, please list that along with the link. Sometimes it won't be stated so if you click a link and its no longer free, then that promo must have expired. I've seen alot of free game listings off slickdeals or other blogs. I'll update this when I see good ones. I would post the free games with Amazon Prime, but I don't currently have amazon prime so if those appeal to anyone, feel free to post them since Amazon Prime generally gives away a couple free games a month.
To start off with:
Little Nightmares is currently free with a Steam promotion until 05/30/2021 @ 10:00am (does not say if EDT, PDT, etc. )

Company of Heroes 2, Company of Heroes 2 Ardennes Assault - Limited Free Promotional Package, free for this weekend or until 05/31/2021? It doesn't say exact day it ends.

Steam has made its own hand held game console. It can be used as a handheld or docked to a tv like the Nintendo Switch. Honestly, this looks like a solid hand held. Everyone that does PC gaming has a steam account and most likely alot of games already in their library. 
There are three versions: $399, $529 & $649 depending on the internal storage. Its shipping December of 2021.

The hardware looks great too:

To fix low volume in Nvidia Shadowplay recordings, open the game you are going to record, minimize it, right click your audio icon, open volume mixer, scroll to the right until you see NVIDIA Capture Server and the game. Set both to 100 percent and turn your volume up to 100%. Control the volume of your speakers or headphones with an in-line volume control. The PC must have volume set at 100% to record at full volume.

The new PlayStation 4 firmware update will include external HHD support for game installation. Finally. I honestly didn't realize the original PS4s even had USB 3. They are also finally adding custom wallpapers via screenshots. About damn time. The wallpapers in the online store are complete garbage. I'd still prefer to use my own .jpg files like on the PS3, but modders used that feature as a way to hack the system which is why we never got the functionality in PS4. Using a screenshot is completely fine with me.

Nvidia is launching an online game streaming service called GeForce NOW.
I'm going to quote myself here from another topic:
With Playstation having it's own streaming service and now Nvidia making it's own service, having to own physical consoles and PCs specifically for gaming might come to an end within our lifetimes.
The downside to the Nvidia service is the cost. I've been seeing the numbers "$25 per 20 hours of gaming" floating around alot. If so, thats a hell of an expense for now.
