Subject 1:
Something like single instance challenges, determined in the menu after pressing prestige. Maybe add on a marathon modifier to the next world, or deathworld, but these only gain you points once you hit a specified higher threshold.
Each modifer should do SOMETHING to your benefit, but only once the threshold is passed. Like once you get to space, now you'll receive your scaled prestige points AND all subsequent (non challenge) runs will have double inserter speed or something. I'm sure you get the idea from here and can take it however you wish.
Subject 2:
More purchasable challenges with other mod integration. This one I have no idea if it's implementable or not. Just hear me out.
Perhaps, if rampant (fixed) is installed, there are purchasable challenges for enabling the AI, and another for each new enemy, as well as another one that will change the max level of said bought enemies, and one for demolisher attacks. I don't really know what's achievable here, I'm practically spitballing. In a similar vein, there is also a newer mod called Enemy AI Enhancement/smart enemies, that possibly could have purchases for the various components of its challenge. Note, these are effectively random, I just thought since I already have one idea here, I should add my others anyways. No harm to it. Thank you.
