Excellent game! I finished it after 7 1/2 hours but it gave me a major headache for the next two hours and I´m a person who actually never gets motionsick even with weird FOV FPS but I guess Prey found my weakness. I enjoyed the game a lot though, and would rate it with a 8.6. I did like Q4 tiny bit better in comparision but Prey is still an excellent game filled really nice features and new ideas. Looking forward for Prey 2.
