I don't intend this as a slight, but you must not follow %Souls games very closely at all. The community practically worships Miyazaki. You can't go one page on any of the given subreddits before stumbling across a mention of him.
Granted, he's a director and maybe not specifically the lead dev - but that's a reflection of the size of modern games. Aside from indie titles (where authors, like Notch or John Blow, are in fact very well known) - AAA games employ such a staggering number of developers that singling any one of them out is almost impossible. Hence, whoever guides the creative vision (in this case, Miyazaki) is the one whose name becomes synonymous with the title.
- Cliff Bleszinski (Unreal, Gears of War)
- Jonathan Blow (Braid, The Witness)
- Toby Fox (Undertale)
- Chris Roberts (Wing Commander, Star Citizen)
- Hideo Kojima
Notch, Markus Persson (Minecraft)
Toady One, Tarn Adams (Dwarf Fortress)
That's a great point. I was definitely referring to AAA games, above. We are certainly in the midst of an indie renaissance (goes back to playing Hyper Light Drifter).
Hidetaka Miyazaki, director of Dark Souls and now president of From Software, is quickly becoming one.
The latest "game developer celebrity" on my list is Kenta Cho, I guess.
