I ran a Google search in incognito mode so that my browser history wouldn’t affect the search, and “interactive novel” only came up once, that being the COG link; all the others were redirects from “interactive fiction” due to Google appearing to treat it synonymously.
Putting “interactive novel” in quotations got me 82,000 results instead of 131,000,000 without the quotation marks, so it doesn’t seem to be that popular a term. The majority of those appeared to be articles from “mainstream” media (i.e. non-gaming) doing a coordinated recommendation of Black Crown (basically three articles from Globe & Mail, the Guardian, the Atlantic giving a recommendation for the same game with similar descriptions). Nothing from a major site offering such games (like Steam or itch.io), nor from games journalism, nor from major gaming discussion sites.
For comparison with other terms, I got the following number of hits:
- “Interactive Novel”: 82,000 results
- Interactive Novel: 131,000,000 results
- “CYOA”: 2,490,000 results (yes, I realise this probably includes the paper format)
- “Visual Novel”:: 6,470,000 results
- “Interactive Fiction”: 773,000 results
- “Choice of Games”: 5,230,000 results
- “Twine game”: 23,600 results
That’s a sample size of one, and the number of hits is never particularly indicative of anything, so your mileage may vary. But in general, I don’t think it would be incorrect to state that “interactive novel” is not that well-known of a term. Not as well-known as CYOA, or VN. The first article for me stated Fallen London as an example, and the first genre that springs to my mind regarding Fallen London is “browser-based game”.
CYOA might be a technically wrong descriptor for the genre, but when has that stopped people who play games from giving them the wrong name? The Total War series is Real-Time Tactics, but it is commonly called an RTS game. There are some people who prefer to use Civilization-style game in lieu of 4X; “Grand Strategy” can vary depending on whom you ask. The simulation category on Steam is cluttered with all sorts of stuff I wouldn’t consider simulation, and Counter-Strike: Global Offensive is one of the best-selling “strategy” games on Steam and has been for years. Sure, there is some strategy in CS:GO, but I doubt anyone would actually call it a strategy game.
People will describe games however they wish. People can attempt to steer them in a direction, but that will not always work. I remember when people used “walking simulator” solely as a pejorative. It’s still a pejorative in part, yet people are more comfortable with using it. It has in part moved away from its pejorative nascency on hardcore gaming forums to a term in the gaming vernacular, used by journalists, game devs and the gaming public. Game devs would probably prefer the genre not be called a “walking simulator”, but people understand what that is now, for better or worse. (And People will probably continue calling it that until they think of something better.)
