Lego Stunt Rally. Super simplistic one button racing game with a built-in track editor, talking\reacting heads and basically a fun trailer that, probably, oversells what the game really is: https://youtu.be/50YQLd2y7jM

I don't think I'd play it now, but I greatly enjoyed it back then and now it's interesting to think of it later and understand how various limitations made it's production and gameplay more streamlined and accessible.
