Just because i don't know this and i'm curious, i ask:
The developers of a mod, that want to integrate some addon made by someone else into their main minecraft mod, must respect some legal obligation that the owner of the addon have due to the copyright or can integrate it also without permission? or a developer have noway to see some of the addon of this mod integrated?
I asked myself this... because IC2 have some important addon that are actually part of the mod infact... and i can't understand why these addon aren't actually integrated into the main mod...
i'm thinking about addon like charging branch, advanced machine and compact solars (and some other that really add intresting and unique features really inline with the HAYO way of think )... i dunno how many time their are there, and how many people add that addons to their IC2 like fondamental part of that... so i'm confused...
It's a legal problem, or an integration problem, a game balance problem, a way to respect the creators of the addons (or maybe a lazyness problem, it come to me the idea that the dev haven't in mind to integrate any of the addon because the addon dev update their addon alone, so less work? )
No charges to anyone... i simply wanna know why...
