Hey all. Always enjoyed reading everyone's suggestions on more unknown games available during big steam sales.
I'll start off with one that I have been a fan of for a long time: Death Road to Canada
This game is like a zombie action Oregon Trail like game, where you manage supplies and fight through hordes of zombies on your way to the safe haven of Canada. Only US$3.74 right now and well worth it imo!
Donut County is only $3.89. It's a short, funny, cute puzzle game where you make everything fall in a hole. Really good.
Digimon Story Cyber Sleuth is $12.49 and a much better 80hr RPG then it has any right to be. And I never even touched the second game in the collection!
