I checked the history on wiki and am now certain that Michael G. IS NOT Michael Gough. Seems that there were a few revisions on wiki where ppl stated that Gough isn't Michael G.
AS I have said before, the voice actors in videogames during the mid 90s where most likely americans living in Japan, not necessaily professional actors. Apparently, the person who removed the wikipedia credits of Harry Mason (main protagonist in Silent Hill,) forgot to remove Richter Belmont. Regardless, I emailed Gough if he voiced Richter, which I am certain he hasn't.
Someone on the interweb assumed that because the voice actor for the konami games during the '90s is named Michael G., he has to be Michael G0ugh.
