There’s also a valid key pre-brood war that was something like “1234567890123”

Brood war didn't have its own keys. Both 1234567890123 and 3333333333333 worked for StarCraft.

All 'G' was valid for Quake 3. I was surprised to find this out from my friend's 11 year old little sibling.

I used a key gen for quake 3 when it came out. Was surprised when I was able to play online. Told my friends who were not able to play online. I guess I was just lucky my key was an actual key!

That feels like some dev being lazy and adding backdoor easy to type keys for testing stuff
