I love all those games you mention... I barely play any games, but I managed to catch all of THOSE... and of course MYST when I was younger. I actually fell down a Myst hole after reading your comment, went to your fansite and had to watch that whole 'Origin of...' video and the postmortem... damn. Inspiring. I was surprised to see ol' Robyn and Rand say some of the things that I say about games lately... especially about wanting a place, not a game, not an experience, nor even necessarily a story...
Anyway, I'm totally inspired now... more worlds after this first little taste (or 'Ages' if you will, haha) has been the plan, as soon as I find another spare 300 hours...
