Gaming

Accursed Farms - Best known for the "Freeman's Mind" and "Civil Protection" Series, Ross also makes the "Ross's Game Dungeon" series, where he reviews games.

Ross has taken a bit of a break from his usual content to mostly focus on Stop Killing Games, A campaign to try and stop game publishers from destroying what customers have paid for.

Ahoy - Previously known as XboxAhoy, Ahoy doesn't upload often, but when he does, the result is a high quality video about varying topics, such as a game series or mechanic.

Humour

Ashens - A remnant of pre-corporate Youtube, when you could make a popular channel by just recording yourself. Ashens reviews various products and features british humor.

It's a bit of an acquired taste, but if you decide to try watching him, I recommend watching these videos to get a taste:

Retro Computing

66Scribe - Focuses mostly on retrospectives about Apple Macintosh computers.

LGR - Known as Lazy Game Reviews, a name that is most inaccurate! LGR puts lots of effort into his videos. He mostly focuses on 95/98 era computers.
