Spoilers ahead: for the puzzle and the movies/games
This post assumes you've already solved the puzzle. It reveals all categories and their connections, and discusses plot details, endings, and spoilers for featured movies/games throughout.
Ecco the Dolphin (1992) was created by a Sega developer named Ed Annunziata after he had a dream about dolphins speaking to an alien intelligence. The game asks you to navigate increasingly abstract underwater environments, communicate with sea life, and eventually confront something that is never properly explained. The final levels are considered some of the hardest in Sega's history. The hint booklet that Sega eventually bundled with reprints was not satire. Players were genuinely stranded.
Games: Fortnite · Apex Legends · PUBG: Battlegrounds · Call of Duty: Warzone
The four titles that built the battle royale format into a mainstream genre. The idea is simple: drop everyone onto a map, close the zone, last person standing wins. Execution separated the field.
PUBG: Battlegrounds launched in early access in March 2017 and sold 30 million copies by December of the same year, breaking Steam's concurrent player record in the process. It was not a polished release. The idea connected. Everything about the presentation was secondary to the format working as designed.
Fortnite existed before its battle royale mode. The original game was a paid co-op survival project. The battle royale addition was built as a side project in roughly two months and released free in September 2017. Within six weeks it had more active players than the original game had ever had. Epic gradually stopped pretending the original product was the point.
Games: Virtua Fighter · Tekken · Mortal Kombat · Killer Instinct
Four franchises that established how one-on-one fighting games work. Health bars, input-based specials, combo systems, finishers. Every fighting game that followed them uses some version of the same structure.
Virtua Fighter arrived at Japanese arcades in 1993 as the first polygon-based 3D fighting game. It looked completely unlike Street Fighter II or Mortal Kombat, and some players found the depth-based movement disorienting at first. The AM2 development team spent a significant part of production working on the physics of weight and impact. Fighting game designers have cited it as a reference point ever since. The franchise never became the commercial giant that Tekken did in the West, but its influence runs through the genre.
Mortal Kombat reached the Super Nintendo in 1993 with its fatality sequences removed and replaced with grey sweat. The Genesis version kept the blood, toggled behind a code. The difference in sales between the two versions was significant enough that it contributed directly to the industry creating the ESRB ratings system the following year. The hearing that preceded it was not particularly informed, but the outcome was practical.
Games: Spelunky · Axiom Verge · FEZ · Minecraft
The category most likely to be missed. All four games look like they came from studios with some headcount behind them. None of the titles advertise how they were made.
Axiom Verge is probably the purest example in this group. Tom Happ built it over seven years while working a full-time software development job, during evenings and weekends. He programmed the engine, designed every room, drew all the art, and wrote the narrative without assistance. It shipped in 2015 and reviewed as though it had been made by a competent small team. Most players assumed it had one.
FEZ was built by Phil Fish over roughly five years. He designed the levels, wrote the code, and created the art. Richard Vreeland composed the soundtrack independently. The development process was captured in the 2012 documentary Indie Game: The Movie at a point when the project was in genuine difficulty and it was not clear the game would be finished. The mechanic it built around, rotating a 2D world inside a 3D space, is simple to describe and genuinely hard to exploit well.
Spelunky existed as a free PC game years before the commercial version. Derek Yu built the original in 2008 using Game Maker, alone. He coded the engine, drew every sprite, and designed every room himself. The freeware version is still available and is effectively a complete game.
Games: Sonic the Hedgehog · Crash Bandicoot · Spyro the Dragon · Ecco the Dolphin
Each title gives you both the character's name and their species before you press start. Sonic (name) the Hedgehog (species). Crash (name) Bandicoot (species). The formula is the same for all four.
The category will catch anyone who pattern-matches on "classic 90s animal mascot platformers" and stops there. Three of these are platformers. Ecco the Dolphin is a swimming puzzle game with science fiction elements and no platforming whatsoever. The genre is wrong. The naming convention is identical.
Spyro the Dragon launched in 1998 and was notable at the time for a camera that worked properly. That is not a low bar being cleared. Third-person 3D games in 1998 frequently had camera systems that made them hard to play. The Spyro team spent a significant portion of development solving the camera problem before handling the rest of the game. The result let players move through large 3D spaces with a fluency that still holds up.
Today's CineLinkr puzzle includes a hard group built around courtroom films where the verdict was already decided before the trial started. The least famous film in that group is also the one most worth tracking down if you have not seen it.
