It's a solid time, definitely is a more interesting use of physics than stuff like asteroids imo, especially since it gives you the direct info on how fast you are going in each axis so you know how to adjust and land safely. I don't know if the emulated versions I've played are just simplified in controls or if I'm just cracked at lunar lander, but I always felt like the game is either too easy to land on the high-scoring targets. The main objective is to score as much as possible, but since the game lets you add extra fuel at any time simply by throwing more quarters at the machine getting a high score is trivial. Truly the first pay-to-win video game. But I guess the real fun comes from the simple act of moving the lander and playing the game, so really who cares about score. If you find it at an arcade, I'd suggest throwing a quarter into the machine, it's def worth a few plays.
