If we can continue this....

Lately I was searching about SAO and somehow went to this its really cool but its abandoned right now im pretty busy so I can't continue it but if someone likes it

To be Honest, I don't think they is much need for that, since PocketMine has well evolved since then. But if one of PocketMine team wants to think about that in the future... It may be a possibility. But like I said, They isn't much need for it. Most of the upcoming updates(major updates) will be shown on the news part of the forum, or the forum home.

Nice idea though

Plus. That's a php, and now we are phar (compile of many phps)

The change is in the API. The file format isn't a difference; we have script plugins now.

Also, things possible in Alpha_1.3 were also possible in the new API. (Am I a bit outdated, still calling it the "new" API?) PocketMine development goes forwards, not backwards.
