how exactly would this work? what if i want to use several mods?

Why would you want to do that? (Genuine question.)

#3791:

Doesn't that risk overwhelming the player with too many choices, not all of which will be good and many of which have only slight differences from each other, in the same way as e.g. a sandbox game with a detailed world settings selector?

is this bad?

I would say so. It makes it more difficult for the player to have fun.

#3792:

why do we allow people to execute arbitrary programs on their OS? doesn't that risk overwhelming them with choice?

No. The overwhelming of the user comes when multiple entities create software in the same niche and, rather than cooperating to fill the niche most optimally, compete with each other to make their own pieces of software fill that niche, overwhelming the user with, you guessed it, too many options of which not all of them are good and many of which have only slight differences from each other.
