Exists exclusion, when You could benefit using aggressive legal policy. If You are really big corporation, You could surround niche of game with Your own copyrighted content and patents, like CPU vendors, each have hundreds of patents. In this case, owner of game, will risk to begin great legal war if he tries to sue You. But this is race of arms, very like Cold war. To be safe, Your investments should be big enough, to compete with what have owner of game. For example, to compete with Microsoft, You should spend hundreds of millions for copyrighted content and patents, but if Your competitor smaller, may be enough few tens of patents.
