CaliforniumI've only played this game for about half an hour. It can best be described as "super trippy".
It can also best be described as an homage to Philip K. Dick, which immediately makes me recommend it for your consumption.
If you enjoyed Richard Linklater's adaptation of A Scanner Darkly, then this should be right up your alley. There's no rotoscoping, but you will recognize the visual style immediately.
One caution: it's not running entirely smoothly at 2560x1440 on my GTX 970. Puzzling.
