Did I hear someone say: "Wha?"
Does anyone remember Crono? I do, and before he disappeared from the face of the Earth I remember him announcing a very large SKF level that didn't have a name. If memory serves me correctly he expressed strong feelings towards SKF 1.0.1 when it came out, as he noticed (like many of us) the considerable drop in frame rate that came with it which apparently made large portions of his jumbo map unplayable. Still though, playable or not I'd love to have seen it before Crono disappeared. It's release was estimated at around the same time as GSN's Temple Of The Pen and my own Cathedral Of Chaos, but now it's vanished into the mists of time and become a legend of Sketchtopia.
Speaking of time, I also remember GSN announcing a level to be named Shrine Of The Seasons, in which the player chooses a specific period of the year to explore a magical forest in. I think I'd be correct in the assumption that I'm one of the few to have played it's BETA, as I don't remember it being released in the Junk Trunk or any later topics. The level contained great visuals, including four nifty 3D season orientated arches! I strongly recommend GSN to add this to the Junk Trunk.
Finally, an elephant never forgets, and neither do I. Edwards claimed to have a level in the works named The Frozen North, which had gotten near the status of being a BETA. As to what happened to that map is beyond me...
