I Love YTtalk
I'd love a review, if you don't mind 
I'm trying to find areas to improve on, so if you spot any, I'd be happy to hear it 
For your channel:
I LOVE that your top banner explains what your channel is about. (So many people don't take advantage of this!) I like the bold thumbnails! The fonts and colors are great. I'd just make sure that they're legible when so small. A few of them I had to really pause to look at to read.
I'm glad you use playlists, especially for channels with a lot of content (or potentially a lot of content), they're super great for organizing and for visitors to find things easily. Don't forget to add descriptions in them though for metadata
I'd also recommend spicing up your about description. It's the text people can read when they hover over your username, so it's pretty important. I'd address more of what your channel is about, your schedule, any other important information, and maybe some sillyness if that's your style.
My main other suggestion is to upload more often. Gaming channels have HIGH competition, most can't get away with less than one a day unless they are doing something really unique and high quality. It might not be possible for you, but I definitely recommend trying to get on some sort of schedule. It helps show you're active and gives people something to look forward to. "Oh, it's Wednesday, x uploads videos on Wednesdays! I gotta go check it out!"
Hope that helps! Best of luck with your channel ^^
