The fact that suggestions can get large enough to require fragmentation to cover makes me want to slam my head against a wall. Especially considering that this suggestion does not actually require any part of the original suggestion to function. This suggestion would've been better served as a standalone. Its nature as a piggy back actually hurts the credibility of the suggestion in my eyes.
With that aside, a lot of these ideas seem less like a Minecraft 2.0 and more into personal preference. Which is the point. You're not going to end up suggesting something you hate, after all... BUT... I fail to see how it would be significant enough to demand a marriage with the original concept of a separate mod-workshopped minceraft.
Cerroz said it best,
The biggest issue here is it's too ambitious and too disjointed. I personally support colored lights! It's an enormous suggestion with an amazing amount of detail, and I'm a bit disappointed that there wasn't a link to each individual suggestion included in your blanket. But that's the thing. It's tailored to you, it's your blanket. I can never completely enjoy every square of the quilt you weave. Even if I enjoy most, there will be some I dislike. Some irrevocable coincidence where I do not like what you like and throws the suggestion into the turbulent seas. There's so much here to ask people to hop aboard on...
There's too much to convince people to like. I like colored lights, I like connected and random textures. I do not like volumetric lag rays. I do not like the change to the lighting system in regards to difficulty. I do not like bloom or reflective surfaces. That's 2 passes out of 6 using only this limited rubric.
This is where the suggestion hits a fatal flaw and shoves my final nail into the coffin sealing a no support. Had these myriad suggestions been able to exist outside of your hastily constructed umbrella and given individual attention; they would've gotten a lot more support from me.
POSSIBILITY OF IMPROVEMENT?
Yes, it's possible to redeem this suggestion and get me to support it. But this requires OP to root out specifically what he's after. The original post was definite in purpose; creating a new Minecraft version with mod support natively. It was ambitious but only had a single goal.
Here? It's a shotgun blast at a board of wishful thinking. Find ONE topic that desperately needs improved, and work toward it. If the primary goal is colored lights, I'd rather just go and support the already existing thread. If the primary goal is focused toward some other untapped potential and you can put your capable hands toward that singular goal then you'll find much more purchase.
