[REQ] Outsourcing actual gamedata/story/platforms/events to a mod

Hi. I thought about creating a mod with an completely alternative story/events/plattforms etc.
But as i see it’s just possible to ADD things to the existing game.
It would be great if you could outsource the actual gameplay to a (or more) mod(s). This would also make it easier to see the actual timeline for adding things to the actual game.

Beside this: thank you for this game. it’s really fun and i spent lots of hours playing. THANKS!
