Criken!
https://www.youtube.com/watch?v=H9HhYAGIWdkSome sorta North Murrican. Content is often FPS shooters, but he mostly just plays for the funny bits. Is usually really quiet, and likes making dumb faces when given the opportunity.
Light to moderate swearin'.
Birgirpall!
https://www.youtube.com/watch?v=js04iW7JVEcSome sort of Swede, I think? No special focus on any genre, but also plays for the funny bits. Usually does 'I Broke: [game]' videos, which are bug/ragdoll and AI weirdness sorts of videos. Much louder than Criken, laughs a lot. Usually has other people talking in the background.
Moderate to heavy swearin'.
SeaNanners.
https://www.youtube.com/watch?v=FDQx-guzx2sI used to watch he, but his vids have been really boring lately. Plays GMod multiplayer games most often, which are named in the video title. Videos are extremely short highlights clips, rarely more than 5 minutes, often more like 3 or 4. Other LPers show up in his vids a lot - Markiplier and Cry, and GaseousMexican or whatever (who is one of the real highlights for crazy voices, as the above link shows). Once again, funny bits. Facecam. A seemingly rare trait for LPers, also: he's actually
good at video games.
Pretty heavy swearin'.
Critikal, or penguinz0!
https://www.youtube.com/watch?v=7oaH3VighGUNonsensical rambling while playing terrible games you say.
Pretty heavy swearin'.
DARK SOULS, YOU SAY?
DamnNoHtml, aka Jund on Livestream.
https://www.youtube.com/watch?v=rgJQp4TbSlMDoes some derpy stuff, is pretty good.
Unsure of swearing.
Limit Breakers.
https://www.youtube.com/watch?v=2P1eKThZG-gI don't actually know anything about them except that the above is my favorite Dark Souls 2 video so far.
DarkProjectMayhem!
https://www.youtube.com/watch?v=GnQ2wK5L5QQSpiritual+ successor to RedRosie, in that he uses the same character and is quality. Creative shenanigans, using the more indirect spells of the game, and trolling.
Minimal swearing.
Then there's the usual array of EpicNameBro, OnlyAfro, VaatiVidya, Yukas, Yamimash, Mriwont4get, etc. Shout out for GrimDisaster, though, who isn't active at all, but is still the best for
Wrath of the Darkwraith and Manly Miner Men.
BradPhusion.
https://www.youtube.com/channel/UCNu61DlWxat2deDH3c0Y2nwI'm not a big follower of his, but I liked his SCIENCE! of gravity generator asteroid rail-guns in Space Engineers.
Minimal swearing, I think.
DarkWolfDeltas.
https://www.youtube.com/watch?v=xTRQLNlbHKgI don't really watch she either, but she's got a longplay of Sakura Wars 5 up, so she's a baller.
Macey Dean!
https://www.youtube.com/watch?v=2HK24KzXeLo#t=1287DED. Did KSP videos, with a really nice birth-of-space-travel series of corporate warfare and militarized KSP ships. All stock.
Minimal swearing.
I also watch Scott Manley, who is cool, but he's been mentioned already.
