In The [board] Games Journal, Greg Aleknevicus writes that German Games are Fraudulent.
His basic complaint is that in German board games, the game mechanic and the theme are often completely disconnected:
The point to be made is simple?the wholesale grafting of a theme onto a set of mechanics is dishonest if those mechanics have no real world connection to that theme. Can a game really be about exploring the Amazon if it can easily be re-themed to the terror of the French Revolution? Is it realistic to simply add floors to an existing skyscraper? Did ancient explorers really decide the orientation of the islands they discovered?
This, I think, is the most important aesthetic question in video games. It’s not interactivity vs. narrativity (the open vs. the predetermined). The most important question is the rules (mechanics) vs. the fiction (theme). It’s really what my Ph.D. was about, but it’s a question that pops up all the time: It’s always straightforward to assume that the fiction of a game is arbitrary and unimportant compared to the rules. However, fiction matters, but in strange ways and with different degrees to different people.
For example, the hardcore RTS players who first picked up Age of Empires would recognize the game as an RTS, and think of it in that frame (rules). But someone new to games might think of it in terms of medieval wars (fiction).
Oh, and Frank Lantz also discusses the issue in Rules of Play.
