Can’t wait for the game engine to delete my filesystem and then be really very sorry about it.

IIRC, Elite used lookup tables for trigonometric functions on certain target platforms (maybe the NES) because memory wasn’t as much of a constraint as computing performance. It’s a barrel of game compressed into a pint of code.

All of the alternatives eventually run into the same “Will my banking app work on it?” problem. The absence of a healthy app economy is the one thing that can’t be fixed by throwing software engineers at it, and it is what caused the death of Windows Phone.
