Upon learning of John Carpenter's interest in video games and his interaction with GiantBomb, I couldn't resist the urge to introduce him to the legend that is Persona 4, as well some of the other MegaTen games. His website features the option to send him an email. I'm not sure if it goes to him directly or to the website's administrator, but either way I hope he eventually reads it. I tried to keep the message as succinct as possible while still emphasizing why I think he'd find the games interesting.
Here's what I wrote:
Are you familiar with the PERSONA and the broader MEGAMI TENSEI series of video games?
If not, I highly recommend that you give PERSONA 4 GOLDEN for the PlayStation Vita a try. It's a murder mystery with lots of surreal elements, a cool art style, and offbeat Japanese-style humor. I think you'll appreciate some of the references to your films such as THE FOG and THEY LIVE as well as other cult classics such as David Cronenberg's VIDEODROME. Despite the anime influence, it's the kind of game that can be enjoyed by people who don't watch much anime. It's an RPG, but in addition to being one of the best examples of the genre available, it's also accessible to people who don't play many RPGs. It's lengthy, but that's why playing it on a portable device like the Vita is ideal. You can play in short intermittent bursts and more easily fit it into your busy schedule. Trust me, this game is so good that it justifies the price of a Vita alone.
The PERSONA games are spinoffs of the larger MEGAMI TENSEI franchise. While these games are stand-alone titles and do not need to played in order, they all tend to involve teenagers/young adults with the ability to summon and harness the power of demons in a modern fantasy setting, e.g., a post-apocalyptic Japan. My second favorite Persona title is PERSONA 2: INNOCENT SIN, which draws from H.P. Lovecraft's Cthulhu mythos, and is one of the surprisingly few video games in which Adolf Hitler appears as an antagonist.
If you like PERSONA 4, there are many other MEGAMI TENSEI games worth checking out. This is a brief introduction to the series: http://www.technobuffalo.com/2014/05/25/shin-megami-tensei-beginners-guide-where-to-get-started/
If you want a much more in-depth primer which explains the lore and the history behind the franchise, see here: http://www.hardcoregaming101.net/megaten/megaten.htm
Particularly noteworthy is STRANGE JOURNEY for the DS, which features a storyline and setting very similar to THE THING, complete with a suitably atmospheric soundtrack.
Likewise, CHRISTINE the killer car is present in some of the earlier games: http://megamitensei.wikia.com/wiki/Chris_the_Car
All of the PERSONA games are playable on the Vita. Many of the other essential MEGAMI TENSEI games are playable on a PS2 or PS3, although there are a few that are exclusive to the Nintendo DS/3DS.
Given your predilection for horror/fantasy/science fiction and the cult movie aesthetic, I can't recommend these games strongly enough. I think you'll find that they're some of the most imaginative, stylish, and endlessly fascinating games currently out there.
The HardcoreGaming101 guide is substantially better than the TechnoBuffalo one, but I included both because the latter is much shorter.
Now all we need is a John Carpenter Endurance Run sponsored by GiantBomb. :)
