This does bring up a few existential questions for me:
1. How far could this be taken?
2. What are the differences between Plasma 1 and 2?
3. Why was Cyan so interested in moving the Uru engine over to Plasma 2?
4. If this can be done, what's to stop us from doing the same thing with the Myst 5 ages?
This tool could be taken fairly far, it hands the keys to the MO:UL kingdom over to anyone that wants them with little to no knowledge needed. So far Cyan hasn't said one thing or another about this going on so I am crossing my fingers that they are looking on this the way I am.
"The Care and feeding of Uru" Remember that line?
If the best possible things all happen in a nice neat little row Cyan will need people that are already passing familiar with the basic changes between Uru:CC and MO:UL. If all the things that need to happen to get a "official" server running again don't happen Cyan is really no worse off letting people play with the MO:UL files then they were when they chose to "ignore" the Uru:CC hacking as long as it stayed offline.
But however it goes I would love to see the possibility of merging URU:CC, EoA, and MO:UL into one game as that is probably as near as we will get to what Season Two should have had. <Shrug>
