I have a case of a TAS I once worked on:
HyperZone.
Hyperzone is basically a rail shooter of sorts. There is a strictly finite quantity of enemies to shoot, so if all of them were shot down, that would be a way to define 100% completion, correct?
The part I stopped at basically had the game flood you with enemies, and it is easily possible some of them fail to spawn because there aren't enough empty enemy slots. If they don't spawn, they aren't a scoring possibility. Based on the troubles I've been having trying to TAS that next part, it may be impossible to get 100% kills, so 100% kills is invalid due to impossibility, and maximum kills is not a valid 100% Vault completion goal, so my TASing goal fails to comply with this.
There is something the game awards you for reaching score thresholds, new machines to fly with better capabilities. There is a finite quantity to this, and once you get the final machine, there are no further rewards in score. If you want to tie this "hard, known maximum" as a 100% completion thing, I will tell you that meeting this score threshold in an any% goal is trivial in TAS conditions, with the only questionable detail being the machine swapping animation. Therefore, by triviality, that "final machine" goal is not a significant change from any%, and is not to be accepted as having appreciably different content.
The absolute last fallback of allowing maximum score to differentiate from any% would at last catch my TASing goal. But if the "final machine" goal takes priority as a measurement of completion, then I will submit there doesn't exist a meaningful Vault 100% goal to be viably submitted. As a result, score is still an unacceptable goal in Vault conditions, despite the supposed fallback.
This is the line of thinking I'm dealing with at this point. A bit confrontational. Please tell me otherwise.
For that matter, I still don't want to read and analyze the discussions that took place, as now these thoughts have taken hold and driven my emotions again in the wrong direction. I just don't want to deal with the subject, but now for a different reason.
