Game Summary:
Towns, a city building and management game mixed with an RPG that draws inspiration from titles spanning Dungeon Keeper, Dwarf Fortress and Majesty. Instead of playing the hero who delves deep into the dungeon, players oversee the town that houses and caters the hero's needs.

Along the way, players can craft unique weapons, obtain randomized loot and build a settlement capable of holding back the forces that rise up from the active dungeon upon which the town sits.

Game Summary:
3079 is a futuristic, open-world action first-person role playing game, and an alleged lovechild of Minecraft and Fallout, with a block-like world, futuristic action, and role-playing elements played in a first-person perspective. 3079's randomly generated areas, buildings, items, quests and characters make it an entertaining open-world experience.

You are sent to a world that is under constant war, and it is your job to find out the cause of this war and hopefully bring peace. You can work with either the Humoids or Neanders to help achieve this goal. Be warned, there is more to fear than just the warring factions on this planet...
Wyv and Keep

Updates planned monthly.

Game Summary:
Wyv and Keep: the Temple of the Lost Idol is a lusciously pixelated 2D co-op puzzle platformer. Dubbed as a more fiendish version of Blizzard's classic The Lost Vikings, the game features two young treasure hunters venturing into the land of Amazonia.

Take control of the duo and use teamwork to solve mind-bending puzzles, navigate challenging action sequences, and find hidden riches deep within an ancient temple.

Play by yourself, with a friend locally on one keyboard, or online, dodging fiendish traps, evading cannibalistic pygmies, shopping for hats, and even exploring an active volcano. Even create and share your own puzzles with the included cartographer.
Current minimum price is only $5, and it's more than worth it for Towns alone. If you get any bundle this year, make it this one, because Towns is truly unmissable. I bought the bundle, despite owning both Towns and 3079, just because I want to own Towns on Desura.

Hurry, though, only 3 days left to go.
