While googling the other day I came across these two videos of a stream Arthur did with ArchonTheWizard not long after Grim Dawn went into alpha release. Although it's about GD, there's also quite a bit of info from Arthur about Titan Quest which is why I'm posting them here. I hadn't seen them before because I wasn't doing things like watching Twitch TV back then. The first one is rather long as Archon was doing a 36 hour marathon stream, although it cuts off around the 4 hour 40 minutes time. The second video is the continuation of that.
