I am starting to stream predominantly Heroes of the Storm games with commentary or sometimes a bit of music. I'm currently around Rank 6 Hero League, I hope to give out some useful pointers but I'm also open to advice!
I will also, from time to time, stream Starcraft 2 and Hearthstone Arena, and I'm considering putting up the odd RPG or 4X game if there's any interest.
I tend to stream after 8pm CET for a few hours on most week nights and some weekends. You are welcome to drop by any time.
