I'm starting a video game development company and am having trouble finding information on the legal formation and legal operations of doing so. After searching, I believe that forming an LLC is the right choice. There are currently six team members (including myself) with two owners. We will be selling video game software via iTunes and also online. Is the best choice to incorporate in Pennsylvania (where we are located) or in a different state, like Delaware? Since these games will be bought from people all over the globe and not just in the state of incorporation, will we need any kind of license to continue business? Will we need any other type of business license? And my last question is concerning registering the business name and DBA filing. If we incorporate, do we also have to register our business name and how do we go about that? If my company were to be called "Game Company" (for the sake of this question) and we incorporate as "Game Company, LLC" would we need to file a DBA if we were just going by "Game Company"?
