Impossible to say because Stern don't publish production numbers.
Going on the number of games available these days - Terminator 3 or Striker Extreme would be my guess.
?
why would you say those two titles?
TSPP, ACDC, Tron, Spiderman, LOTR, Stern has sold enough of these titles to run them through production multiple times
I would think that both T3 and Striker Extreme would have been one run and done
