Here are some of the things I've acquired for free over the last week or so. They all seem to still be available for at least a little while through Drivethru or their company's website for a little while.

Melee - Steve Jackson Games. The foundation of The Fantasy Trip. I'd more excited about this except I own my original copy and my Kickerstarter copy and PDF. Still really cool though.
Teenagers from Outer Space - R. Talsorian Games
Fantasy AGE Basic Rule Book - Green Ronin
Deadlands Player's Guide and Marshal's Handbook for Savage Worlds - Pinnacle Entertainment (Through their website.
I also discovered an online shop called Exalted Funeral that has been giving away some games. Through them I got:

Witchburner
Wish You Were Here
Lorn Song of the Bachelor
The Lapis Observatory
Troika!
Disciples of Bone & Shadow
These were one shot/one day things I grabbed and are unfortunately no longer available. Thank you to these companies too.
I got a whole slew of games from Onyx Path Publishing.
