Before I say just post it, ever asked a friend how they think of your voice? Did they say its fine? Did they say its unique? I mean most people don't like their own voice but others might just like it or atleast they don't hate it.
Though I don't have a gaming channel, what I do is talk from start to finish, imagine how hard that is to post without someone to tell you that you actually have an ok voice. And and and! I prefer a soothing voice (almost monotone) voices for let's play videos because I can't stand listening to people who have over reactions when gaming.
Also, I still don't like listening to my voice and editing is a nightmare (I want to mute it but then I can't coz how am I going to sync my voice to the material lol) but people say I have a cute voice or something similar to that so its bearable.
