In most games whose focus is combat, as indicated by the genre to which they belong (action, action-adventure, rpg, action-rpg, etc etc), the player character has a predetermined degree of power, with limits on how low or high can that power go.
For example, in the God of War games, you've got Kratos, an angry, bald killing machine against whom the average human soldier holds no chance whatsoever, while mythological creatures and gods give him a run for his money.
Games like Uncharted show that Nathan Drake is capable of going toe to toe with any single enemy, but larger amounts of that kind of enemy can present trouble.
Then you have a game like Dark Souls, where even the lowliest enemy can kill a player if he isn't careful. And once you complete your character's build (let's say that happens at SL120), your only rivals (read: things that can actually kill you) are elite mobs, lategame bosses and gravity.
The question is: In any game where combat is centric to the gameplay, what kind of degree of power you like your player character to have?
Or, which is the level of epicness you aspire to reach?
