I'm hoping to find a GM that is willing to run a single player D&D campaign. I've always been interested in seeing what it would be like.

The only request I have is that the campaign would be a sandbox style campaign.

If anyone is interested, let me know.

I am looking at launching a sandbox game based on the Fallcrest setting from 4e, but with 5e rules. That said, you should check out the game Bones of Giants, which is a sandbox designed for single characters in a really cool setting.
