My other main takeaway from the Direct is that while a Tetris collection from Digital Eclipse is super cool (disclaimer: I worked on their Wizardry I remake, if briefly, so take what I just wrote for what you will), as someone who was just beginning to think about finally plunking down the money to have Tetris the Grand Master 3 in the home (I already have 1, but 3 is my favorite by far), I'm feverishly doing an over/under in my head about the likelihood it's among the remaining games yet to be announced when they're making a point of emphasizing how many of them have been Japan exclusive until this release.
On the one hand, it would be nice to not potentially drop... six figures in yen just to have more authentic arcade Tetris to play at home (or maybe, maybe even finally have prices on it come down a little), but on the other, it feels like any TGM would be one of the legally weirder ones to work out, even if you would figure (hope?) that at least some installment or other of that gets featured. 3 feels like the most realistic choice for a number of reasons, especially so as to not step on Hamster's toes and I'm sure not holding my breath of them ever touching any PC-based games for obvious reasons, but... 🤔
If any of y'all have opinions, I'd love to hear them because for as much of a Tetris head as I otherwise am, I can't say I actively keep abreast everything that goes on with Arika and that series. 🤷
I was gonna say I had a longer reply queued up that I was scrapping in favour of a shorter version but this version's not much shorter so whatever:
you can take Nintendo dropping a NES Tetris NSO announcement right alongside this one as a sign that they're not giving their games to this collection, and I really don't believe Sega will participate, either... which immediately eliminates a massive chunk of the biggest and most culturally-significant commercial Tetris games from this comp, to the point where you almost wonder why they'd bother doing it without them. TGM doesn't strike me as a complete impossibility—their VP Mihara has spoken publicly about fielding interest from Arcade1UP or some other similar company, only for said company to back down when they conceded they weren't confident they'd be able to satisfactorily reproduce the originals—but I certainly wouldn't trust DE to do a flawless job, either, or to even match the existing Hamster versions.
(EDIT: this comment on the Steam forums all but confirms no TGM: https://steamcommunity.com/app/3180240/discussions/0/4423185135322890837/)
Like, they've pledged a "recreation" of the original Electronika 80 version. Neat! They have a bunch of BPS' Japan-only FC/SFC games, perhaps most notably the Chunsoft-developed Tetris 2+Bombliss, designed and advised by an all-star team of collaborators with the intent of rectifying the mistakes of the BPS' FC Tetris. Cool, if you're a Tetris nerd, and probably far less cool if you're not, especially if you're not a Japanese person closing in on middle age. Hatris, because why not. The Atari arcade game seems like a given, which certainly isn't nothing. (EDIT: or not, I forgot that it's owned by Warner Bros.) What else, though? How about any of the zillion-selling games that one might reasonably expect from a Tetris collection?
Putting aside the futility of trying to assemble a commercial anthology around a series as fractured as Tetris, there's no doing justice to the history of the series as a museum piece, either: The Tetris Company could not give less of a shit about the history of the series beyond perpetuating the Pajitnov/Rogers folk story to whatever minimum extent will allow them to continue cutting deals for tetromino-shaped bath salts or whatever, and any history that centres on them or is forced through their filter is necessarily going to exclude all of the vast and varied movements that gave this game a culture worth commemorating, because it runs counter to their cute little licensing business. I mean, the anniversary they're commemorating isn't even a real anniversary—they just up and changed the supposed origin date back in 2009 because they felt like running a 25th-anniversary campaign that year.
tl;dr: it's not going to have much of a through-line as an assemblage of software, nor will it include most if not all of the most popular, globally-recognised and playable versions; it's doomed to offer only the most basic, sanitised, marketing-copy version of "history"; and it's a complete coin-flip as to whether the games it does contain will even play adequately (because, for all their work to reposition themselves as a high-end curation studio, a lot of their emulation work's still very rough around the edges).
Every one of the games listed in the trailer is BPS, so I think it's safe to say this is what's happening: it's "Tetris documentary" as corporate mythmaking. This is the authorized documentary problem, something that's become a real problem with streaming service documentaries in recent years - everyone wants the access benefits of making the "real", "official" documentary even if it means you're just telling the specific story a brand wants people to hear.
The early history of Tetris is defined by the non-BPS Tetrises - not just Nintendo Tetris (which is being rereleased separately from this), but the home computer ports, the arcade versions, and so on. There's a Tetris story you can tell by focusing specifically on BPS Tetris and The Tetris Company, but that's a Tetris story - the story of this company and its role in a wider culture, not the story of the culture itself.
