Back in 2021, during a late evening in April, and several hours into the night, I created a simple game which simulates a SpaceX Falcon 9 landing. I incorporated as much real physics as I could using Newtons second law to calculate the acceleration. To get more realistic acceleration I used technical data I had about the Merlin rocket engines and the weight of the booster etc. to calculate the rate of weight loss while firing the engines. And suddenly it had become a game :)
