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.
Times & Galaxy gives its first robot reporter an unpaid internship. We built artificial life, sent it into space, and immediately found a way not to pay it. At least the newsroom offers intersolar cat shows to cover.
Games: Dead or Alive Xtreme Beach Volleyball · Beach Spikers · Super Volley Ball · Power Spikes II
Beach Spikers reached Japanese arcades in 2001, a year before its GameCube port. That's why the date on this board may look early if you remember it as a home-console game. Sega AM2 handled development, a useful detail to keep in mind before trying to squeeze it into the Sonic Team row.
The court is the connection. Dead or Alive Xtreme Beach Volleyball takes the sport to the beach, while Super Volley Ball and Power Spikes II give it an indoor arcade treatment. Video System developed those last two; Power Spikes II arrived on Neo Geo arcade hardware in 1994. The sport survives the change of scenery and hardware. Your ability to return a serve is less dependable.
Games: Neon White · Neon Abyss · Iron Harvest · Mercury Meltdown
Neon gets two seats at the table. The rule asks for an element name in each title, not four different elements, so both Neon White and Neon Abyss qualify. Iron and mercury round out the chemistry. You can solve this row without finding a shared mechanic, which is fortunate because the games aren't making that easy.
Iron Harvest sends infantry and mechs into a dieselpunk strategy setting. Mercury Meltdown asks you to tilt a stage and guide liquid through it on the PSP. One sounds like a military procurement problem; the other sounds like something a lab supervisor would prefer you hadn't spilled. The common property is printed on the box.
Games: The Occupation · The Painscreek Killings · 2064: Read Only Memories · Times & Galaxy
The journalist in The Occupation researches the Union Act in a story set in 1987. Janet in The Painscreek Killings takes an assignment from her editor to investigate an abandoned town. They might look like detective-game protagonists, but their jobs explain why they're there. Finding a story has become considerably more dangerous than filing one.
Read Only Memories gives its journalist a missing friend to find. The original full computer release arrived in October 2015; the title gained 2064 with the 2017 update. This board uses that 2015 release year, rather than treating the expanded title as an entirely new game.
Times & Galaxy makes the profession unusually explicit. After interviewing sources, you assemble an article with its Build-a-Story tool. The publisher describes an unpaid robo-reporter intern with seventeen cycles to prove it belongs. A robot can handle interplanetary travel, but apparently still needs to demonstrate enthusiasm in a probation meeting.
The shared job is more precise than "games where you investigate things." The settings and interfaces differ; the person doing the investigating has a newsroom-shaped reason to ask questions. That distinction is what makes the reveal feel earned.
Games: Sonic Adventure · Phantasy Star Online · Billy Hatcher and the Giant Egg · Samba de Amigo
Sonic Team is a studio name, not a promise that a hedgehog will appear. Sonic Adventure is the obvious anchor, but Phantasy Star Online turns the row toward an online action RPG. Billy Hatcher and the Giant Egg and Samba de Amigo make the range harder to ignore. The studio was not taking requests for a single mood.
The original Samba de Amigo reached arcades in 1999 and Dreamcast in 2000. This is that Sonic Team game, not the later Wii version. Billy Hatcher first appeared on GameCube in 2003, which also stops "Dreamcast games" from becoming the answer. Remembering where you played something can help, then betray you.
The click comes when you stop searching for a shared hero or genre and recognize the people behind the games. Sega published all four originals, but publisher alone is too broad: it also published Beach Spikers, which Sega AM2 developed. The studio boundary is the useful one here. Even the giant egg has paperwork.
The robot internship is still bothering me. If your chassis doesn't need lunch, management will probably call that a benefit.
For a different kind of bargaining disaster, October 29's CineLinkr puzzle has ransom demands alongside rodent heroes who would rather get on with their own adventures.
