Simply tailor games better to the actual narrative. For example smarter but less numerous enemies and or have allies helping you.
A good example would be Mount and Blade Warband. Until you're leveled fairly high(or a mounted archer fighting infantry,) anything more than a 1v1 is fairly difficult. And even when you are highly leveled, other more dangerous characters are still difficult to engage when outnumbered. This is however mitigated by the fact that you command an army. If you get talented at fighting 1v1 or small groups, so long as you have an army with you, you can rack up kills because the enemy will be dealing with all your soldiers thus taking the pressure off of you. This is probably the best compromise for a game involving a lot of deaths in the story.
