Either your game will be popular, or it won't. If it's not popular, then no one will buy it, but neither will they pirate it. The only pirated copies out there will be people who would never have paid for it. And at least your name is on it. If it IS popular, then lots of people will pirate it, but even those pirated copies will come from somehwere - original, paid versions. You have to be prepared for the fact that your title will probably fail. That's the inherent risk you are taking in exchange for the possibility of making money doing something you love. It's the essence of capitalism. And the fact that such a thing is even possible is a minor miracle.
Finally, find some way to add cool tangibles or addons to your package. For example, expansion packs that can only be purchased with a valid key, or large, professionally printed maps of the terrain, or a mini-book that compliments the game. All of these things will make some people want to own an original edition.
It's important, for perspective's sake, to recognize that evolution is not necessarily incompatible with Design. In some cases, Design is even compatible with the man-from-primordial-ooze theories. When it comes to that, you have some random, unidentified force causing unpredictable mutations in an otherwise closed system. Some people choose to believe that the random, unidentified force is willful and others choose to believe that it is truly random.
Darwin was also known for having expressed that his theory showed that (and how) blacks were genetically and naturally inferior to whites.
1) Get yourself an executive champion - someone with authority who understands the potential liability of deploying pirated software. Offer to audit and document all the company software, including applications that people need/use without a license. Work together with management to develop a strategy from there. BTW, this is great for your resume.
2) Quit. If your moral scruples are in jeopardy, explain to your management chain that you can't work in an environment that is exposed to these legal liabilities. Either they'll change or they won't
Most importantly, don't be a wuss. Lay it out straight for people, level the threat of resignation if it gets to that, and be prepared to follow through. There's nothing worse than that guy who bluffed about quitting and got called out.
This place just isn't big enough for all of us. We've got to find a way off this planet.
