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. )

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:

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.

Am I the only one suffering from steam sale fatigue? Maybe its just me but ever since they changed the store to the design it is now nothing in the store appeals to me anymore. Its probably because of the massive influx of every game from every independent developer. Theres so many games on there that I never look at what new games came out anymore because in any given week 40+ new games were released and 250+ games are listed in their weekly sales. I stopped looking and only pay attention to humble bundle sales now. Even with the steam sale going on now I don't see any huge sale thats leaping out at me to take my money anymore. Sure I still have a backlog of games but there seems to be less and less new AAA or indie games that I'm interested in for PC. Unless its a game I want for console I hardly look at the steam store anymore even though I use steam on a daily basis.

I got my Steam Link in the mail today. Its a nice little device. But right off the bat I had an issue with it. Not with it per-say, but with Amazon. They shipped me a used Steam Link. wtf. All the stickers and tape were broken and somebody obviously returned it. The previous owner's name was Justin. Here is a link to my review:

Anyway, the steam link does work amazingly good.. if connected with a LAN cable. Wifi would probably work a hell of a lot better if I upgraded my router to something that actually supports 802.11ac, mine only connects as fast as 802.11n. Because of this my steam link is practically unusable in my living room while connected over wifi. I actually own a 25 foot (might be 50 foot, its really long) ethernet cable so it was no big deal for me to drop a cable line down the flight of stairs from my PC to my living room to try it out. With a hard line connection like that the steam link works so good, its as if my PC is in the same room and connected to the tv with an hdmi cable. The steam link auto recognized my wireless xbox 360 pc controller. The wireless pc dongle stays powered on so whenever I want to boot up the steam link, I only have to hit the xbox button on my controller to turn it on. Once I get a new graphics card I'll be able to play my entire library of games on my TV in surround sound. Oh.. and it looks like I should be able to play all my origin games with it too. As long as the streaming connection is established with Steam, I can alt-tab out of steam and my TV is now broadcasting my desktop and any and all programs running. I should be able to open Origin and play every game just as if I was running it through steam. The steam link has 2 USB ports, so if I don't want to play a game with my controller, I can simply unhook it and connect a mouse and keyboard.
Maybe one of these days I'll upgrade my router and see if this can actually stream over wifi correctly. If not, having to run a hard wire cable is a bit of an annoyance.
