[joshkrz]

You know, the first Abe was slightly different. I thought I was the voice of ‘Hello’ in the first game but actually it was Josh Gabriel and that was cleared up later. We both did all these recordings. He did Abe’s voice by biting his tongue and saying ‘Hello’. I wanted him a bit more goofy and a bit more legible. So, it’s funny that on the first game it was actually Josh on the button and in the second one it was me.

MOD EDIT: Corrected URL to point to part 2.
