Its only a mess because people have made half arsed pages or just haven't made pages for things they've added to it, resulting in dead links

You realise that'd be much easier than adding all the pages all over again? Because the vast majority are functional and still applicable.

That's like saying that Halopedia should make a different wiki for every game that's released, its just kind of pointless because you'd still have to copy across half the stuff.

What would we need to carry across? Race pages? They need to come. Nation pages? They need to come. Event pages? They're pretty useful for background fluff. Tech pages? Many are still applicable... We're copying across more pages than we would be able to simply delete. There's only a handful of irrelevant pages, of which are just player nations who left...
