Head to head
Which one will break you first?
Two fingerprints on one grid. Both are scored through your profile, so this answers the question for you rather than for the average player.
Age of Empires II: Definitive Edition is the harder of the two for you, by 2.2 points. The gap is widest on strategy, where Age of Empires II: Definitive Edition asks considerably more than The Last of Us Part I. If you want the gentler run, start with The Last of Us Part I.
Axis by axis, biggest gap first
THE LAST OF US PART I
Grounded strips the listen mode and most of the ammo, which turns stealth from an option into the only plan that survives a room.
You will lose sometimes. You will not mind.

Sustained pressure. Progress is earned.
