Open Source Halo Dedicated Server

[Skyline]

but seems to be a very hacky way of doing things

What? Hacky way of doing things not I thinky. It calls a library; nothing hacky about it.

as it not only uses more resources

It all depends on what you're going to be doing. Using .net requires much more resources and can cause more potential problems.

And tbh, would you rather work on a half arsed attempt and complete it with hardly any difficulty at all, or if we create a server from the ground up and will be working on something challenging.

I would rather have a working server created by the game's makers with a simple modification to enable certain elements that would make it easier to use than to have a server created by someone asking for help on how Halo works.
