Unfortunately, after I started this thread, I realized maybe it would've been better placed in the "Suggestions" category.
Oh well...
Animated linking panels are a very cool idea. They'd take up some space (given the sheer number of ages in the game) but it'd undeniably be worth having them.
As for "working with volunteers", well, yeah, I've suggested as much on these boards, repeatedly - get a small group of part-time Cyan Worlds team leads (someone writing story, someone designing puzzles, someone as art director) - and then have a big group of talented fan volunteers - artists, programmers, musicians - to bring those story/gameplay/art designs to a completed form.
The creative vision, the design, would be Cyan's, but the work of developing that vision into actual finished ages would be up to the fanbase.
BTW, sorry for posting the sparklie spoiler - shouldn't have mentioned which age the broken sparklie was in.
I guess I forgot that I was in the non-spoiler section when I posted the initial message.
Yes, Cyan Worlds can convert Myst V worlds to Uru - but it'd be a debatable business decision to convert all of them as it'd reduce the perceived value of one of their major sale products (Myst V) if all the worlds in that game were available for free in Uru.
I'd argue in favor of converting a variety of small pieces of those ages at first - little parts of Myst V's worlds that aren't heavily woven into the slate puzzles and which wouldn't require much redesign to function in Uru.
For instance, the Todelmer pod would be easy to convert - it's a self-contained space and wouldn't need to be changed much at all to work in Uru.
Cyan doesn't have the resources to make major redesigns of Myst V content and puzzles right now anyway - but there are several little enclosed or almost-enclosed bits of Myst V's worlds, like the Todelmer pod, that might be fairly easy to move into Uru.
Cyan can release Myst V material into Uru bit by bit, starting with the simplest bits - in between organizing completion of genuinely new areas (Kahlo), or reopening closed ones (Gahreseen Wall).
But this is all hypothetical right now, it's contingent on us reaching CAVCON 5.
