Decided to go ahead and make this public, didn't get any feedback if there's anything unpacked, so if there is anything that's missing please let me know. (Also this is for Community Edition, not vanilla Portal 2.)
I replayed Portal 1 after over 10 years and finished it in roughly 2,5 hours (+- 10 minutes, didn't check the time precisely). I don't remember it as THAT short!
Tell me the most useless fact about Portal you know. This can be about the lore, the games themselves, the development, etc
