I want to present Factorio to a friend

Which youtube video should I sent him so he can fall in love?

Official trailer and gameplay trailers are amazing and short, start there.

It depend on your friend, some videos are fun and super high paced, others slow and full of technical explanations, with many in between.

The trailer is nice no ? You'd prefer something more exciting ? showing more the combat ? the large scale building ? the trains ? the fun and careless gameplay ?

The 2014 trailer contributed to trigger my initial purchase. It has been updated a couple times, here is the last version from 2020 :

A free demo is the best advertisement a game can have.

The demo will get him hooked for sure, only thing is that after that the game itself can be a dissapointment because it does not have any extra 'story' missions like in the demo.
