This is mostly an RPG trope, but can be applied to any game with combat elements and some type of Life Meter. This trope is about Video Games where it's easy to inflict ridiculous amounts of damage, resulting in combat practically just being about attacking first. Actual skill is most likely still involved, but it will be more about agility (Dodging, improvising) than intelligence (Min-Maxing, planning ahead). This trope can happen due to various reasons; Higher offensive stats than defensive ones, an abundance of One-Hit Kill moves, et cetera. Please note that this has to apply to both Player Characters and enemies, or it's just a case of Glass Cannon.
