I checked out his profile. He looks kind of familiar, and especially his alias. Game over Johnny, wonder if he's on the forums here
He's on Sega16 a bit (as 'timemaster' I think) and he is very into the collecting side of stuff with a full US Sega collection and a couple other Nintendo fullsets as well. I think he's much more active on Nintendo/SegaAge , but I don't think he's on PCEFX at all.
I will say, he has had a very methodical take on sussing out all the weirdness of US Sega releases which is always neat for me to read about. He also is the only other person besides myself that actually collected the US Pico set which I find hilarious when you said other people are actually into the Pico now.
