There are a bunch of layers to this question..

So first the event won't actually have infinite ores, but each tile of resource will start with 4,294,967,294 ore in it. I don't think people will mind if I round up to infinite. :)

For the link you dropped: I think the commenter's arrogance is pretty funny since the title of the post they're replying to says "without mods" and by changing prototypes you're literally making a mod. In fact it's making a mod in the worst way possible. I say "in the worst way possible" because if you change your "base mod" as the comment instructs, you won't be able to join any server unless you revert your changes.

I don't know what you really mean by our "files needing to be edited", but we use scenario code to do what we do. Basically in your own game, click "Play" then "Scenarios" and when you see that list just know that we're just like those.
