Concord still lives rent free in my head from time to time.
it's by far the biggest failure in the games industry, it was relatively boring, no one will ever enkbowledge it in the mainstream and it's very likely that Sony itself has not learned anything from it.
and despite that, I will still remember it.
btw, iirc you can still find copies of the sealed gape on ebay, I remember looking up and aparently the game had a Saudi Arabia release ( I do wonder what regional changes they made for different parts of the world )
also, there was a few months back, the story of some developer putting up for sale a developer's certificate/studio goodies around it, from what I've heard, Sony told them to take down the auction.
