I feel like getting back into the swing of things and posting free games again, so here's 3:

https://store.steampowered.com/app/493540/Figment/
https://store.steampowered.com/app/582660/Black_Desert

Both are free-to-keep forever until 3/9. Get them while you still can.

And for the people who use EGS (I don't personally):

https://store.epicgames.com/p/rise-of-industry-0af838

Same date applies.
