That depends on whether DLU prefers to implement features fully or to rush to be the first to open testing. From what I've seen of them they still have a way to go before having a smoothly playable implementation.
Our project aims at providing a playable and sustaining experience, with more content than just the basic questline which can be finished in a day. We'll continue to release videos so you'll be able to see our progress yourself. Once there's enough content in the videos that we consider suitable for sustained playing, we'll open a public but closed testing instance, with the aim of eventually hosting a fully public server.
Implementing all this will take a while though, and we're only doing this in our spare time, so it's hard to give any estimates. At the least it will still be several months before reaching a suitable level of progress.
I would in fact like a more closely working together community, which is why I'm available in chat for questions and why I've published the information we've found on packets and file structures. This documentation is what has made it possible for other server projects to persist, and some server projects have shared their contributions back, which I am grateful for. However DLU so far hasn't shared any of their findings, which I find disappointing given that they seem to be the second most advanced server project. Fragmentation was what caused the collapse of the original LUNI server project back in 2014, so I hope that the community as a whole won't experience the same fate.
On a lighter note, we're almost due for our next video in the series, where we'll progress to the monument, which requires some server physics I'm excited to show in action. Stay tuned!
