-How to gain an emotional connection with your character-
1. Giving your character a relatable personality. Make them be in situations the majority of people can relate too.
2. Making your character emotional. You don't want your character to be a brick wall with zero emotion, but you also don't want a character with an overwhelming amount of emotion. Find the middle line between the two.
3. Make sure you're play has a driven story. The audience will be more inclined to like a character if the story is good aswell.
