I was never a fan of how StarCraft 1 is supposed to be played.
It had a map editor that allowed scripting and people used it to make tons of other games inside of StarCraft like tower defense games, drawing party games like you would see decades later on mobile, and RPGs of every franchise imaginable. There's literally thousands of unique games out there on archive websites.
Some of my other picks have already been mentioned so I'll go with an obscure answer: Cpt. Olivia Rhodes from the VR game Lone Echo.
She is by far the most realistic and immersive NPC I have ever had the fortune of experiencing. The storytelling and immersion in Lone Echo is S tier. The game itself is in my top three VR games with Half-Life Alyx and Boneworks.
Homebrew on the PSP was actually insane though. You could play everything up to the Nintendo 64 on it and even some PC games like quake. I played so many super Mario world ROM hacks on it
On the one hand, it's unfortunate Wikipedia is having to spend extra human labor to deal with that. On the other hand, I'm always down for poisoning LLM data sets
Which is in turn a reference to the film, They Live
