I'm not too sure how to reply to this. I watch several regularly and have been exposed to others I wish I hadn't to put simply. I'll go through the ones I follow, the ones I would rather just quit and those in between.
RegularsGame Sack A fairly entertaining show chock full of games some we've all heard of others not so much. The episodes tend to be on the long side of 20+ minutes but they can cover a lot of ground in that time. Usually do episodes pertaining to a genre or console and list some good and not so good games along the way. All without resorting to wall to wall toilet humor to carry the show.
ProJared I just like the way he presents himself. Usually itemizing what he loves and doesn't when it comes to games he reviews. He doesn't really stand out though and can be rather dry and boring to some.
The Completionist I give this guy props for what he does. There is no way I would put myself through that just to "100%" a game. It's interesting what some devs do when players 100% their games. I'm too lazy for that so that's what he's for. lol
The Rageaholic Very outspoken individual and that may be putting it lightly. He has a fairly large vocabulary and isn't afraid to whip it out and wave it around. Reviews tend to be short, clocking in at 10 or so minutes average. He's not for everyone though as he in his usually verbose way tends to be rather crass and vulgar.
JonTron I um, eh... Well, yeah I don't know why, I just do. DON"T JUDGE ME!
Wish they still did,StillGaming This was my first YouTube reviewer. His videos were short and entertaining. I liked his style. I still enjoy watching his review of Peggle. From what I understand health reasons and pairing up with that disaster Blistered Thumbs is pretty much what killed him off
ClanoftheGrayWolf They might still be doing their content on their personal site, I haven't checked. The 8bit and 16bit Gems series were well done. The way Video Games Work was also one of my faves.
Watch Very Occasionally AlphaOmegaSin Really got tired of his constant ranting and raving.
AVGN James wants to end this you can tell by the dead look in his eyes when you boot a newer video. That and his juvenile escapades has gotten long since stale.
TheHappyConsoleGamer He seems like a straight up, nice guy. I don't watch him. I can't explain why. I don't hate his content, I just don't watch it.
Not if you paid meTheRPGFanatic Ugh. Boring, bland, lifeless. Sure fire coma material there.
ReviewTechUSA I hate this guy. Does nothing but rumor mill and stir the pot.
RetroGamer03/TheGamingRapist/TheWelfareGamer Whatever his moniker is at this time I don't care. This guy is try too hard budget AVGN. Proof positive that Canada can breed ignorant and bat shit crazy just as well as the U.S. does.
AngryJoe I don't know what people see in him. I don't have the attention span to sit and listen to one guy beat the reasons he doesn't/does like a game to death for 30+ minutes. Terrible skits and just boring ass writing. Not a fan.
JimSterling and MovieBob These two gibbering landmasses are annoying as hell to watch. At least I can sometimes agree with Sterling. Both are narcissistic asses.
