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!
APICO, a nice little beekeeping simulator with bee-breeding mechanics and building.
Ages of Conflict: World War Simulator, an incredibly cheap God-game/nation simulator. Not comparable to WorldBox, though. Just a little game for making nations fight and painting maps
