35 years later, Hideo Kojima recalls how the "gruelling" development of his little-known Cyberpunk adventure game left him with a stomach ulcer

Hideo Kojima has recalled how one of his earliest games was a "gruelling" process to develop.

Before Kojima was known for a little series call Metal Gear in the 1990s, he helped develop Snatcher for Konami. The "cyberpunk graphic adventure game," as it's described now, was first released for the PC-8801 and MSX2 in Japan in 1998, and focused on sentient robots killing and replacing humanity in an East Asian city.

Kojima helped write, code, and plan Snatcher. November 26 marked 35 years since Snatcher released for the PC-8801, so Kojima marked the occasion by reflecting on the game's development process, which was apparently particularly painful as the team at Konami had to effectively write their own programming language on the fly.

I was in my 20s at the time, so I was gung-ho. Konami was an action game company that had cut its teeth from arcade games, so no one in the company had ever made an adventure game. Therefore, we had to develop an adventure game system. Furthermore, since we were an MSX division,… https://t.co/5O2HlZl9m1November 26, 2023

The Snatcher team at Konami was focusing on the MSX prior to Snatcher's development, so it actually had zero experience with developing for the PC-8801. Kojima's tweets above make it sound like the team had to effectively teach itself how to program for a PC as it developed Snatcher.

Kojima recalls that the development process was especially "gruelling," and he actually ended up with a stomach ulcer near the end of making Snatcher. Game development is chaotic and ever-evolving, where hundreds of things can go wrong at any point in time, so devising your own programming language alongside making the actual game sounds nightmarish. 

Still, Kojima looks back on the process as
