LOL, It may have sold well due to nostalgia, but did you play it (when it released)?The best thing for Fdev would be to pull the plug on ED and concentrate on a good seller like Jurassic World Evolution.
The gameplay loop consisted of...Repair this fence, Refill this feeder, Inject / airlift this dino.
Every now and then, do it all 10x quicker in an emergency and turn back on some power, then back to the daily grind of refill this feeder.
The game had lots of potential, great graphics, great foundation, the building was ok if not limited, but the things to do where as imaginative as those in Elite... repetition with timers. I can't speak for it now, been a while since I looked back, but Frontier need some new gameplay people, preferably with fun imaginations.
