The important thing in your comment:
It happens regularly that three players end up on the same score within their group in the tournaments I've played, or even 4 players being tied on points. (Abtsein's Expert Terraformers tournament is the example that comes to mind). An example: this summer I was in a group with 5 other players, with a 4-way tie for 1st place: https://boardgamearena.com/tournament?i ... oup_586506
It's not fun when you are facing a loss already if your opponent starts to milk their engine for another generation and builds a monster score. The prospect of a major contribution to a big score differential encourages this. I found it mildly annoying when I first encountered it, on the receiving end of someone inflicting an extra generation when he was in a won position already (that was in an earlier run of the tournament, somewhere in springtime). Now I just factor it in.
This score differential tiebreaker features only in Round Robin group stages of tournaments with 2p games. It seems to be a standard setting for that format. (Perhaps it's used it other tournament formats, but I haven't come across it yet.) Question is: how do you find tiebreakers when 3 or more are tied? Score differential is an easy one to understand and unlikely to need yet another tiebreaker. The logic seems to have been: make it the default. It's easy to understand, and everyone can simply adjust.Where the tie is between 2 players, head-to-head results as tiebreakers would be much better.
