Was this the one where you started in a jungle, and you had to use a first-gen mindstorms kit to explore Inca-like ruins? If so, yes - and that game was epic. Loved it to bits.

EDIT: I think I may be thinking of something else - regardless, found a flash archive of the old games here: http://biomediaproject.com/bmp/lmp/games/lego-game-archive-c...
