If you really want to get picky, ;-) the original Myst was developed using Hypercard by Apple for the Mac. I think it was ported later to the PC, but I don't know what they used. And yes I do know of a few programs that are quite good that have been done with director. So I didn't mean to rain on your parade, just that to be a serious gaming engine, I wouldn't think it would be developed in Shockwave, Not unless something has changed in Director over the last year or two.
