I had a brown sauce encounter today.
I was at Goodwill today, looking for American Beauty for my wife, because we seem to have lost her copy. I also saw Need for Speed: V-Rally on PS1, and picked that up. Pretty cool looking rally car racing game by EA. But found some more of that mysterious brown sauce on the outer-case and had to scrub it off.
Just thought I'd share since there's an unhealthy obsession with brown sauce here at VGCollect, and I'm an enabler.
