I too have often pondered the identity of Nathan. My personal opinion is that it's an alt of Fizzers (even if the state lists differently). His ratings are typically fair and kindly spoken. I think if Fizzer released a new map, it would be a big deal whereas Nathan gives him an outlet to make some more creative less strategic maps without everyone jumping down his throat because Fizzer made a non-strategic or non-traditional map. That's just my opinion though. I have no inside knowledge on any of this.
