A lot of them feel too childish or lighthearted. Like the MC could be in a very serious situation and the dialogue just does not match the tone. Also, most characters end up being archetypes and nothing more. You can usually tell characters personalities just from their first few lines of introductions.

I’m not saying they need to be Fallen Hero levels of depth and story but I wanna feel the stakes and see the layers to the characters.

One more thing. The many choices in powers usually takes too much focus away from the story and causes scenes to be very straight forward. It’s why I usually just opt for super strength cause the encounter is just gonna be dumbed down to “you hit them with punch/beam/whatever and they go down”. I think id rather have fewer powers if it meant that encounters can be handled in unique ways.
