Answer:
an interest group
Step-by-step explanation:
When designing a video game I believe that the best target group would be an interest group. Focusing on a specific interest group will allow you to design a game, knowing that there are people truly passionate about that interest and who will play the game. Targeting an age group makes things difficult because you have to limit your creativity to that age group and even still there may not be much interest in that age group for your category of game. Therefore, an interest group is the best option and gives you the freedom to unlock your creativity without having to limit your game due to age concerns.
