Pandora

I joined a CoC one shot of his, very good for beginners! He took some time at the beginning, before the game started proper, to explain things about both Roll20 and CoC and it's character sheets. Then explained the different mechanics as they came up. He had music that fit the tone and various sound effects to set the mood. All in all, I'd recommend!

He's very willing to work with players to create altered races and classes, and creates NPCs to help fill party roles so that the party doesn't need to worry too much about making sure there's a PC to fill every role. These NPCs never feel like DMPCs, never overshadowing the party itself. The world he's created has been fun and interesting so far.
