do i still need to credit you if i change the entire game, changing the way the blocks look and move, changing the entire system, and changing every single bit of the game and maybe recoding it?
I am super okay with getting no credit for heavy reworks/rewrites.
This is a bit of a tangent but I think about credit/blame through this lens: Shapley value - Wikipedia
As the value of my marginal contribution goes to zero, my due credit also goes to zero.
Shapley values gracefully go negative too; if doing a rework/rewrite distracted you from more interesting or useful projects, then I’m due a (probably negligible) amount of blame for the distraction and so I apologize for that.
