head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Competitive PvP
Classic fighting execution and human prediction atop a famously unbalanced roster.

Execution · Practiced Mastery
Tests shooter mechanics fused with real-time base-building economy against human teams.
Mortal Kombat Trilogy leans Execution (Competitive PvP); Starhawk leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mortal Kombat Trilogy
Dial-a-combo inputs and run-meter pressure demand fast hands
Starhawk
Vehicle dogfights and third-person gunplay demand twitch skill
Mortal Kombat Trilogy leans a little harder on reads, though the gap is small.
Mortal Kombat Trilogy
Human opponents must be baited into unsafe moves
Starhawk
Predicting enemy build placement and pushes matters online
Starhawk leans a little harder on variance, though the gap is small.
Mortal Kombat Trilogy
Movesets are public; nothing hidden in a match
Starhawk
Little hidden beyond fog of incoming drops
Starhawk leans a little harder on optimization, though the gap is small.
Mortal Kombat Trilogy
Knowing the bloated roster's broken tech is half the battle
Starhawk
Rift economy and build-and-battle structure placement decide matches
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.
