Return of Reckoning

I thought I saw a post that linked a youtube account with a series of videos about the scenarios in game.
I'd be grateful if somebody with knowledge of it would link it here, thank you.

The videos you are looking for are by Martok, and you can find them here.

The ones you are looking for all have the scenario name in the title, and there's a bunch of other cool stuff showcasing lots of different play-styles there too. Huge time sink, but definitely worth it!
