Suggest rules clarifications and movies to flag.
When counting some units instead of percents, apply similar logic. Refer to collecting all items as "all X".
I get the analogy being made here. I would state that you're missing one piece, in that, not because the game being unplayably boring is why "passwords" are used, but because the game explicitly wants you to input "passwords" to get randomly created characters, with a few special discs providing special characters. I cannot say if MR or MR2 are "boring" to play without generating a monster via a CD, as I have never played them nor ever will. However, I can tell just by reading this thread that they are certainly intended to be played by inputting "passwords" for new, randomly-generated characters. Given that is a major point of the game, I'd definitely consider allowing an exception for Vault in cases like this.
For the purpose of that rule, I think the usual/unusual specification can only be scoped to the game in question. If it's scoped to gaming as a whole, "unusual" is too broad to effectively classify. MR2 may use an unusual method of gathering input compared to other games on the platform, but that would also extend to any game that requires unique controller/peripheral data handling. If the difference is that other games happen to support the data natively over the controller bus, that's a limitation of the tools, not a fault of the game. It doesn't seem like an enforceable distinction when scoped outside of the gameplay of the game alone.
I also disagree with the continued focus on "arbitrary" when applied to discs being a factor; the data pulled from the discs is no more arbitrary than the set of controller inputs. The data gathered from any given image is small, can be generated/simulated, and leads to a finite and fully handled set of outcomes in the game. This is not a case of hijacking a peripheral IO port and injecting program-altering instructions. It is loading data from a fixed medium using intended and expected game functionality. The data that's loaded in this manner is limited and fair, but currently not included as part of a movie file. I don't see why including this information as part of a submission makes it not objective when everybody has the same ability to craft and introduce data.
I don't know the full history of your interactions with educational games and past rulings, so I will decline to comment on that.
You bring up Moons and Stars, but in your personal estimation, how far is this current submission from meeting Moons criteria? I don't know the future, and other individuals are far more creative than I can envision, but I personally doubt a movie for this game could be significantly more entertaining than what has been shown by NK. I don't think such a movie will ever meet the bar for Moons just by virtue of how the game progresses and the limited options available to a player.
Not allowing arbitrary Discs feels like an arbitrary restriction
I disagree that the rule applies here because it specifically denotes playing the game in an unusual way. Using discs or otherwise is in fact the usual way of playing the game. Not using discs and otherwise would, for purposes of casual play and developer intent, be unusual.
This gets into the grayer area that I mentioned though, and a lot of it is tied to experience. I played this game a fair bit when I was growing up, and all I can say is that playing the game without the ability to use discs feels wrong.
It may as well not be the same game at that point, since it so drastically limits your options. From a TASing/speedrunning perspective, it also takes away a huge chunk of the routing challenge. Those are not objective things that can be part of any set of rules, but in this case do matter a lot for the competitiveness of the game down the road.
However, for the reasons stated in the prior paragraph, this is not nearly as interesting of a problem to solve, nor does it reflect how a typical player would experience the game. It may not make a difference in trying to keep rules consistent, but in my opinion makes any disc-less submissions far less interesting/entertaining to perform or watch.
Finally, I just want to say that if the criteria listed at the end of feos' longpost are taken up as official policy, then it is unlikely any disc-based Monster Rancher game will ever be acceptable on the site. The game, while interesting to optimize, does not allow enough expressive freedom or content diversity to meet Moon entertainment requirements. If that's the way that it has to be, then so be it, but it effectively kills off an otherwise reasonable game choice from competitive consideration.
Putting a different CD into the PSX is not relying on knowledge external to the game, just data external to the game.
A player who inputs a code must know the specific code before inputting it to yield it's result (and it can be generally assumed that the player knows what that result will be before using the code). A player sticking a different CD into the PSX doesn't have to have a specific CD nor does the player need to know the result of the CD used to continue with the game.
Further, the use of the CD is intended as part of normal play, not play enhanced/altered by a secret code/input sequence.
I generally look at codes/passwords/etc. as things that either intentionally make the game easier/harder. The CD swap with the MR games is not a guaranteed result of easier or harder (it could in fact yield a neutral result).
We allow playing unlockable content using in-game passwords Using in-game codes[1] or passwords at the start of a game is allowed if it makes the game harder or if it makes cosmetic changes to the game, as long as parts of the game are not skipped. Using in-game codes or passwords at the start of a game to unlock a special game mode, character, level sets, or otherwise play the game in some unusual way is allowed. However movies of this nature are not considered to be one of the primary branches for the game.
When we speak about codes that are part of a game that we allow for use in certain scenarios, we are talking about passwords that can be entered in a menu, pressing some buttons on the title screen, passing execution parameters or setting environment variables for DOS games, or anything of a similar nature. This excludes things like Game Genie codes or emulator cheating tools.
Required, No.
It's kind of like Generation 1 pokemon games. Through normal gameplay (not using glitches) it's impossible to catch all the pokemon without trading with another player via a link cable attached to another gameboy (an outside source of data). Doing so isn't necessary to beat the game, but it can be used as a resource to yield different/stronger pokemon that may allow for beating the game faster than playing through without trading. (yes I realize the presence of glitches makes this moot for pokemon games specifically, but the concept of the outside resource is sound.)
