Games have been pirated for decades yet the industry continues. If a game is any good at all, expect it to be pirated. Even blockbusters get pirated. It doesn't really matter in the end.
You will succeed or fail based on the quality of your work and whether or not you can convince anyone to buy.
People that are successful in the industry realize that they aren't just competing with the rest of the industry but anything that can distract the customer.
If you are trying to blame piracy for your troubles then you are a loser trying to blame someone else for the fact that you can't make it in a tough market.
