My fav streamer would have to be LIRIK, dudes hilarious! He's mostly known for survival games like DayZ and H1Z1 but he plays basically any new game that catches his eye. He plays viewer voted games during Sundays which he calls 'Sub Sundays'. He also does this thing on his stream called 'LIRIK Hotline' where he sets up calls with his subs and just talks to them which in my opinion is a really cool way to interact with people. He's top 5 on twitch for the most subs (recently just hit 10,000 subs) and he racks up an average of 30,000-35,000 viewers each day which is MAD. He's definitely worth checking out if you haven't watched him yet!
