Could you clarify if you're going to open source the client and provide a deadline? I'm ready to start writing plugins and help if you do release the code. A lot of feedback here were also ignored.
I understand that it's your code, your property, we have no right to say anything. But you're not building any good faith when you ignore people and come here to ask for help. I hear people saying the same thing on Discord, many people want to help but won't if it's closed source.
What's stopping you from charging people $500 for the client and tooling once it's ready? Or to pivot and sell it as your own engine and ignore Ragnarok Online? Why would we not expect your project to fail and get abandoned just like so many others did in the past decade? It's a two way street.
This worries me because it shows that you are trying to move further away from the base game and/or are not following a vision. And that you're not leveraging the power of the community that could write these things for you.
I wish you success and I think you could really change this game for the better. I'll watch your progress from the sidelines to see if you ever open source it and if not this is my last post here. Good luck!
