Game Theory released a video a couple weeks ago and given Marc Laidlaw's recent Episode 3 fan fiction I thought it was well worth sharing. If you've played Half-Life or Half-Life 2 the G-Man is featured in the story and I'd argue is one of the main characters of Half-Life 2. Since G-Man isn't explained well in the games there are many theories online about who he is and the one Game Theory presents is a pretty compelling one. Since Marc Laidlaw is the only author of the Half-Life series answering questions right now someone asked him about Game Theory's G-Man theory and his response was pretty interesting.

I don't want to spoil anything so firstly I recommend you watch the Game Theory video above and then click the Twitter link below for Marc's answer. ALSO if you haven't already, read Marc's recent Episode 3 story(Epistle 3) because we all deserve closure.
