This is not a realistic option. I'm not going to abandon my quite large collection of games - some of which I play weekly to say in touch with distant family - and then start the lengthy, costly and time-consuming process of suing a company that lives on the other side of the Earth. The cost of Sim City is literally half an hour of consultancy work. This means the lawsuit would cost me more than I could hope to gain from it, and I would only be doing it to spite the publisher. If that is my goal, it is a more efficient use of my time to accept the sunken cost, give some negative reviews, and badmouth the publisher.
