It's been a big year for gamers on YouTube. The launch of YouTube gaming has only added fuel to an already impressive fire. Let's Playing is bigger than its ever been, and it's shown no signs of slowing down.
As this year comes to an end, we're looking back at the most successful gaming channels on YouTube. Some of the YouTubers on this list are long-standing pillars of Let's Playing, while others are up-and-comers that are taking the genre by storm.
For the most part, the most iconic names still dominate the field. PewDiePie is still the most popular YouTuber in history, boasting more than 41 million followers. Markiplier has continued to hold a strong presence this year as well, with more than 10 million followers under his belt (though it's worth noting that some of the personalities on this list have passed Mark's subscriber count). Because these two names have been so prominent for so long, it seems unnecessary to include them on this list.
Long-standing Let's Play behemoths aside, here are our picks for the top YouTube gaming channels for 2015.
