Turns out "someday" was today

Hacknet Deluxe is free for the next 48 hours on https://www.humblebundle.com/store/hacknet-deluxe
(you get a Steam-key)

Unreal Gold is currently free on https://www.gog.com/ (for the next 44h)
It should also be free on Steam.

I just realized that Titanfall didn't make the list.
:(

Totally deserved, maybe my most replayed game of the last 5 years.

This breaks my heart.

Mario Kart 8 is the best game in the series. Kind of a bummer that they ruined the perfect item balance of the original in the re-release on Switch.
