RIP to the end of an era.

Was IdTech used outside of Id? Or was it just a Doom series thing as of recently?

Absolutely, the first versions until idTech 5 were open source and a number of important engines, like Source, derive from it.

Wikipedia actually has a family tree that's broader than I remembered: https://upload.wikimedia.org/wikipedia/commons/8/85/Quake_-_...

The CoD series, Source games (Half Life, Portal, Left 4 Dead), Titanfall, etc.

Huh? They were made open source when they were obsolete, Valve did license ID IP for the first Half Life but they paid for it. And that evolved indeed in Source.

Very interesting tree. Today I learned that the engine we used in college classes, ACKNEX, actually wasn't an idtech derivative. I could have sworn.

The relationship was different. When Id licensed an engine, they threw the code code over the fence, and games that used it often heavily modified the engine for their purpose. In contrast Epic put a ton of effort into making the UT engine a polished development tool for creating games.

Didn't love the gameplay but the Indiana Jones game looks absolutely phenomenal.

And ran like melted butter. What a great engine.

Not sure if I'd call that outside Id as its all Zenimax.

This explains the connection: https://en.wikipedia.org/wiki/MachineGames#History

I wonder what's happening to MachineGames...

Skin Deep by Blendo games, which came out in 2025, used Id Tech 4 (despite its age). Super fun game with a ton of personality!

IdTech 3-6 was used extensively by most FPS shooters back in the day.
