I don't understand how you can claim that's a taxonomy, since your genres are not mutually exclusive. You have Action-Adventures as well as Action and Adventure games. I'm not sure why a simulation is not an action game, and so on.
Plus, a cladistic approach can't work because that requires the concept of "common ancestor", and there's no such thing as a clear ancestry in gaming, cinematography or literature, since there's contamination of genres.
Frankly, it seems like you're willing to build on sand.
