We've already seen this happen with GSFs terrain bricks, why not more?
The two big advantages are:
Compatibility: People who use these bricks now would be able to load their bricks onto any other server without trying to get the admin to download the brick mod. It also makes their saves more stable in case the add-ons are lost, deleted, or for some other reason irrecoverable. Seems like all positives to me.
Variety: Default blocks are amazing and already provide us with tons of variety but adding more won't hurt anyone. The people who don't want to use the bricks could simply not use them or disable them if they really wanted to (like GSFs can be disabled but by default come with the game). If the add-ons were enabled by default or build into the game, it would give some people who have "default paranoia" (building with only defaults when they have many brick add-ons at their disposal for reasons such as lost add-ons, comparability, etc) more bricks to have access to.
I don't know, these are my thoughts. I know there's some default purists out there, but if we add more brick add-ons to the default game, then those bricks would BECOME default and then you get MORE defaults to build with.
Perhaps the question is which ones to add to the game? Should we add all of them? Including the prop bricks? Including the filled bricks (Which would be nice because there's like 2000 of these different packs with different names and all are sometimes incompatible with each other and one pack would unify it all and make them obselete)?
IMO, I think any quality brick could be added, from the chain link fences to the poles.
ADDRESSED QUESTIONS!Also, your first point has a flaw:
If you want to put your build on every server, make it out of default bricks.
But if we add more bricks, then more bricks are default!I don't know how much more I can stress this.
a lot of people will not want to search through tons of bricks to find the ones they need. the default set of bricks is fine the way it is right now.
Maybe we need a better menu? I'm sure it could be made way better to display more bricks in less space and be even more intuitive.
Think outside the box on solutions to these problems! :D
