Scenario / Challenge Question

[TheSAguy]

Morning,

I have an idea for a production challenge type mod.
I was looking up scenario's and it looks like it can basically only use vanilla entities. Or is that just for the scenarios that come with the game?
I saw a youtube video of Redmew's Diggy scenario. I really did not even know all this was possible. I hope stuff like this can get a little more notice. It's amazing!

I also don't understand why it's not on the Mod portal? Is there a reason for that?


Before I go down this path a was wondering if it's possible to create a Mod, not Scenario and implement a production style challenge?
Basically I am going to have the player mine a certain amount of resources. But I'm adding my own stuff, so it will have to be a Mod vs. Scenario.

If it is possible, are there any Mods/Examples out there I could look at?

Thanks!
