Making your game general

ITT we discuss how to collaboratively design our games.

So ITT people say you don't need to make a game engine, don't need to make interesting gameplay, don't need music, don't need cut scenes, don't need good writing, don't need dialogue options, don't need to make your own 3D assets, and don't need art.

By the sounds of it, you don't really want to make your own game. You just want to put things together that other people made. But at that point, is it even really yours? Sure, it's faster than doing things yourself. But you lose autonomy over your project. You can no longer call it yours if you just glue together pre-made stuff that you had no part in creating.
