Perfect Dark 64 VS Zero Review - The FPS Reboot Problem of 20 Years

Perfect Dark 64 was the spiritual successor to Goldeneye on Nintendo 64 and had a follow up game with Perfect Dark Zero as a launch title on the xbox 360 and we had the XBLA remaster. How did Pefect Dark 64 hold up against Perfect Dark Zero and why didn't they make more sequels and reboots to the perfect dark franchise? Will we see this series make a come back in 2020 or 2021?
