I’m interested in mystical experiences and what it means to be mystical and feel strange. I’m interested in making games as someone who didn’t go to college, is not only trans but non-conforming trans, is extremely poor, is suspicious and inhumanoid. I get stuck on feelings, on the grain irritating my eye. I’m interested more in the curves of a sentence than the layout of corridors, or modulating an emotional landscape, not racing towards the next grand, simulated vista. I’m realizing how many of my games focus on tight interactions, not spatial branching.

Its a folded-up short story, poem fighting back, game made out of words. Parasite is about what it means to let someone else into your dreams. Below, you will find the trailer, and a description of Parasite in Porpentine’s own words. We are proud to present Parasite for your gaming pleasure. It shows that even directly opposed interests can be stabilized by sufficient diversification of strategies on both sides.To accompany our Games issue, we asked game-creator and interviewee Porpentine if she would make something for us. The model shows that it is not necessary to invoke selective effects of multiple species of parasites and multiple species of hosts to explain this diversity of strategies. The model suggests that, when the change in NRR for different strategies is generated by a random mechanism, which on the average does not favor either player, an antagonistic host-parasite relation will either evolve large numbers of parasite and host strategies or else become evolutionarily unstable. Within these bounds, the probability of a substantial change in average NRR for either player tends to zero as both players diversify. Analysis of the model gives bounds on how quickly each player must diversify, relative to its opponent, to avoid any change in average net rate of reproduction (NRR). This elementary and unremarkable conclusion does not depend on any assumptions about the details of payoffs or the numbers of strategies that the host and parasite currently use. The model implies that it is to each player's advantage to diversify its strategies if the cost of additional strategies can be neglected. For concreteness, the model supposes that the host and parasite contend over changes in the parasite's net rate of reproduction.


To focus attention on the number of strategies of each player rather than on the details of payoffs, the model assumes that the elements of the payoff matrix are chosen at random, once and for all. The model is based on a two-player (host and parasite), zero-sum game. At the level of species diversity of hosts and parasites, the model provides a theoretical basis for Eichler's rule. A simple phenomenological model proposed here shows how evolution by natural selection could explain this diversity, and why the diversity of a host roughly corresponds to the diversity of a parasite. The host also has many types of reactions and defenses. In many host-parasite relations, the parasite has numerous variants, antigenic strains, or types.
