I seem to remember, back in 98 or 99, buying a PC GAMER magazine, that came with a cd (with games and mostly demos), and on it was a RPG-like 2d cartoon animated cell game (or maybe my memory is fuzzy on that), which depicted how humans discovered baby Thrall and how he was raised in Durnholde Keep and... I remember a picture of a human handling baby Thrall, hands in the air... not even sure how the game would go about...
What was that game to be? As far as I know it never saw the light of day, I think it was dropped for incoming Warcraft III (I think that was the story back then).
