Spacewar! (there's an exclamation mark in the name) inspired me to write a modern one player version with gameplay more like the amazing (and free) Waves (https://store.steampowered.com/app/107600/Waves/). It bombed and sold about 9 copies! Here's the Steam page: https://store.steampowered.com/app/2434510/Gravity_Waves/

I also had a take or two at a "Spacewar! for One". Neither made a dent in the universe. :-)

[1] Outer Orbit (closer to Spacewar! and its orbital mechanics): https://www.masswerk.at/outerorbit/

[2] Gravi-o-roids! (featuring multiple gravity attractors and probably the better game): https://www.masswerk.at/gravioroids/

It looks cool!

Thanks! I also wrote Tiny Solar System which is kind of KSP for 5 year olds. https://store.steampowered.com/app/2116950/Tiny_Solar_System...
