i'm a huge youtubers fan! i find so many people through youtube randomly and i end up loving them so much; and they're all pretty well known [a lot of subscribers & their own site].
for games, i usually watch:
AzureBlade49 [aka Azura], Jaymonius [aka J-man], and White Nekos [aka Neko] → they all sort of do their own thing on their own channels, but they also do brawls and stuff together [they're roommates] and they're HILARIOUS! azura is the most subscribed of the three - he does videos such as mario rom hacks, ssb brawls, and a lot more!
ProtonJonSA → he, like azura, does a lot of mario rom hacks and ssbb vids. he's just as hilarious as the other three!
RedDevilDazzy2007 [aka Gemini Dazzy] → he does walkthroughs for spyro games, canis canem edit [bully], and a bunch more. he's really fun and entertaining!
Marriland → he does pokemon walkthroughs. a few days ago he started his soulsilver walkthrough, so if you don't have the game but want to check out its new features, check out marriland's channel! i usually watch his vids to see if i missed anything in my game or to help me out in places i'm stuck at; his site is AMAZING aswell, it has literally everything you need to know about pokemon.
for comedy, i watch:
Smosh → these guys are truly hilarious! i really love their old videos, but their new ones are just as funny. they are the guys responsible for the pokemon theme video.
aand i won't go on, but i watch a variety of different channels, such as makeup channels, dance channels [for sytycd], music channels, and much more! xD
