MonotoneTim for sure. He plays mostly Oregon Trail and Roller coaster Tycoon, with many other games in between, such as Virtual Corporation, Hard Times, and many other obscure games. Last night he was playing a game called My Boyfriend 2, and boy was it hilarious.
He also has a second stream, Not_Tim that he mostly uses for work, playing Puyo Puyo, Ouendan, and for demoing stuff for the main channel.
yea i fell in love with this guy back when he was doing the extralives charity marathons. the feats of charity work he pulled off were just mindblowing. 70-80 hour charity streams, he'd stay away 24+ hours at a time, take a 3 hour nap, wake up and continue. you could hear the marathon taking a toll on him, yet he'd still keep talking, keep telling jokes. it's not like most marathons where they're just organized people taking turns, he was actually suffering for it. it's good to see him getting some attention for all of that. i like his non-offensive style a lot, too many people on twitch try to be shocking or vulgar.
