Play This Thing!
'Mid the Sagebrush and the Cactus raises an old but perennially important question about whether it's possible to stop a cycle of violence. It supports its theme with an ingenious combat and conversation system that keeps the player on edge and forces him to play with some caution for his own safety.
What lets it down is the failure of its writing to convey the human emotions behind such a situation. The philosophical and systematic problems are only problems because of the human capacity for rage and grief -- and Sagebrush doesn't show us those effectively.
