It sounds a bit too restrictive.
What i liked about the Invisible Cities series is the fact that these cities and building Calvino described weren't created through an architectural logical process, but were much more influenced by the passing of time, by the love of men for a dream, by our obsession for self-perfection, by the vertiginous idea of death etc...
In my understanding, an architectural game is more symply a game in which players experiment with and challenge the principles of architectures; just like what Calvino presented us with in his book: cities which challenged our preconceived ideas of why and how a city should be built.
