head to head
Dota 2 asks more than Age of Empires, and the gap is reads.

Optimization · Mind & Math
The original historical RTS of advancing ages, booming economies, and rushing armies.

Optimization · Grand Arena
A deep MOBA where draft theory and adaptive mind games drive every fight.
Age of Empires leans Optimization (Mind & Math); Dota 2 leans Optimization (Grand Arena).
Dota 2 leans a little harder on execution, though the gap is small.
Age of Empires
APM and micro under pressure
Dota 2
Last-hits and spell timing demand precision.
Dota 2 leans clearly harder on reads.
Age of Empires
Scouting and countering human strategies
Dota 2
Drafts and ganks revolve around adaptive opponents.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Age of Empires
Fog of war and map resources
Dota 2
Crits, bashes, and bounty runes add noise.
Dota 2 leans a little harder on optimization, though the gap is small.
Age of Empires
Build orders and eco timing dominate
Dota 2
Item builds, timings, and lane theory are deep.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
