So,
Qvadriga
It hit Steam right before the sale so sort of got lost in the shuffle. Played quite a bit of the non-Steam versoin, finally had a chance to check the Steam version out. It's the exact same.
So Qvadriga won't blow you away graphically or sound-wise, but it's damned unique. It's a chariot-racing sim / chariot-team-management game. You can play the races "turn-based" where it pauses every 10 seconds to let you enter a command for the next 10 second turn, or you can play in "real time" where you enter your action for the next turn during the current turn. The given actions at any moment are pretty basic, mostly accelerate, decelerate, try to maintain control, small or large moves left or right (i.e. 'lane changing') or attack left or right (either smashing with your chariot, or using your whip on other drivers/horses.
But what glorious chaos results. Most of the damage will be stuff done to yourself, as you take a turn too quickly and lose a wheel, or whip your horses a bit too hard and one of them goes down, etc. In single race mode you don't really care, but when playing the surprisingly deep team-management campaign you can get *heavily* invested in your star Aurigas, and watching them being dragged unconscious behind your horses after their chariot disintegrates, hoping they can get it together and run off the track before being run down by an opposing team can be crazy stressful.
Management is fun too; you can build a team of violent bruisers, super-technical race managers, speed demons, etc, by combining perks and training of the Auriga, the chariot, and the horses. And you need to respond to the different race tracks and area tendencies (some tracks are super-crowded, so you need to be tough, some areas of the map have drivers that tend more towards the technical over the physical, etc)
So... yeah. Fun game. Plays exactly the same on Steam as the DRM free version does. Not cheap, but pretty unique.
