Used to work at Rebellion on their IT team. Genuinely a fantastic place to work and the owners seemed to always be super chill. Had a full suit of armour in one of their offices and so many weapons lying around (likely blunt replicas but still really cool).

I wasn't on the game dev team so can't speak for them but I was personally never pushed to work harder and often explicitly told to take breaks.

We also used to have large Unreal Tournament matches at lunch.
