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 3.0 points. The gap is widest on strategy, where Age of Empires II: Definitive Edition asks considerably more than Mario Kart 8 Deluxe. If you want the gentler run, start with Mario Kart 8 Deluxe.
Axis by axis, biggest gap first
MARIO KART 8 DELUXE
Finishing is trivial and winning is not. The item distribution is designed to take the lead off you, so the skill being tested is holding first place rather than reaching it.
Relaxed. Failure is rare and cheap.
AGE OF EMPIRES II: DEFINITIVE EDITION
Build orders are the curve, and the campaigns teach almost none of what the game actually asks for. The hard AI does not forget its economy while it fights.
Sustained pressure. Progress is earned.
