Hammerfight

Hammerfight is about 2D battles of flying machines equipped with various slashing, piercing and blunt weaponry.A unique combat system is based on realistic physics simulation, and it ties the movements of the rider to the movements of your mouse. As you wave the mouse, your rider swings his warhammer, smashing the foe into the wall!
This creates an unequaled feel of the real strike, a feel of the mass of the weapon in your hands. Simulated physics and direct mouse control creates a huge variety of possible battle techniques and an unlimited field for perfecting one's fighting skill.

• Intuitive mouse control
• Realistic physics, breakable objects
• Great storyline
• High quality art
• More that 50 weapons
• 3 additional modes, up to 4 players

Delores: A Thimbleweed Park Mini-Adventure

Also available through Epic games and now also Good old Games

The year is 1988. Adventure game developer Delores Edmund, on hiatus from her job at MMucasFlem Games, has returned to Thimbleweed Park for a quick vacation. While she’s home, she’s making some extra money as a photographer for the Thimbleweed Nickel News. Hey, game developers need to eat, too!

Thimbleweed Park hasn’t changed at all in the year since Delores has been away… or has it?

…Since when is the S&D Diner a five-star establishment?
…When did the PillowBear™ become all the rage?
…Why is Ransome the Clown suddenly winning humanitarian awards?
…How come no one seems to remember that dead body that turned up under the bridge a year ago?
…Can Thimbleweed Park get any stranger?!.

In a town like Thimbleweed Park, a side career in photojournalism is the least of your problems…

Crusader Kings II

Went free in October 2019 but looks like not posted to Cheapies.

The Dark Ages might be drawing to a close, but Europe is still in turmoil. Petty lords vie against beleaguered kings who struggle to assert control over their fragmented realms. The Pope calls for a Crusade to protect the Christians in the Holy Land even as he refuses to relinquish control over the investiture of bishops - and their riches. Now is the time for greatness. Expand your demesne and secure the future of your dynasty. Fill your coffers, appoint vassals, root out traitors and heretics, introduce laws and interact with hundreds of nobles, each with their own agenda.
A good lord will always need friends to support him. But beware, as loyal vassals can quickly turn to bitter rivals, and some might not be as reliable as they seem… Stand ready, and increase your prestige until the world whispers your name in awe.
