GOG (which used to stand for Good Old Games, but now hosts modern games as well - all DRM-free) has three games for free:
Delores - A Thimbleweed Park Adventure (not the game Thimbleweed Park, which was available for free on Epic a few months ago)
Ascendant - which appears to be a fighting game
War Wind - real time strategy from last century.
Not sure how long this giveaway will last, or whether it is permanent. GOG has other games that are permanently free in its store; you can find these by going to the GOG store and selecting the price filter āFreeā on the left-hand-side. (Many of these are demos or DLC, but there are also a lot of full games.)
Edit: just noticed there is also a button to filter out DLC, which reduces the list length.
I think I should also mention something non-free, from itch.io:
Thatās US dollars of course, but for 1,658 (at time of writing) largely games, but also game creation assets and possibly a few other utilities, I suggest the price is eminently reasonable! The cause is definitely worthy, and that USD5.00 is minimum recommended: you are welcome to pay more.
GOG is offering a game for free, it is " Europa Universalis II" and the offer is valid for about the next 86 hours. You need to sign up to GOG if not already a member.
Humble Bundle are offering a great deal to those who like to tinker with producing art on their computers. This isnāt free but the pricing is still great with the full package which includes Corel Painter 2020 currently in the $40 range (Australian). Link to the offer below:
