It's hard getting known on just let's plays, unless you happen to be really charismatic and get a pretty lucky break. See what you can do to add something new or different to the gaming video scene, whether it be how you comment on it or how you decide to edit it all up.
There's really no formula to making a Let's Play "better". What makes them entertaining is the host. People like HCBailly, Chuggaaconroy, PhantomSavage, and PewDiePie are some of the most famous Let's Players because of how personable they are. It's you inviting others to play a game along with you! You can be crazy, silly, funny, whatever you want just so long as you play the game all the way through. (100% runs not included) Just treat your viewers like your best friends and they will go right along with you. A happy host is a happy audience.
Just don't go overboard and for the love of God, DO NOT PERFORM IT STRAIGHT. I have yet to see a single Let's Play I liked where the host just spat out information in a Ben Stein voice.
