I have a few more resources noted down, if you'd be interested for the list:
- https://www.indiegala.com/showcase
- https://www.amusement-center.com/project/egg/game/?mode=search&sssort=desc (service itself is paid so kinda like Prime in "free with a fee")
- https://freebies.indiegala.com/
- https://steamdb.info/freepackages/
- https://www.app-sales.net/
- https://steamdb.info/sales/?min_reviews=0&min_rating=0&min_discount=95&sort=discount_desc
- https://itchclaim.tmbpeter.com/
- https://shaigrorb.github.io/freetchio/
- https://isthereanydeal.com/giveaways/
Should I list the NSFW resources too?
