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.

Optimization · Systems & Chaos
An autobattler decided by economy curves and shop variance management.

Optimization · Pure Optimization
Sequencing global nation control and tech investment against an alien timetable of hidden incursions.
Teamfight Tactics leans Optimization (Systems & Chaos); Terra Invicta leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Teamfight Tactics
No mechanical inputs of note
Terra Invicta
Strategic menu simulation; no physical dimension exists
Teamfight Tactics leans a little harder on reads, though the gap is small.
Teamfight Tactics
Scout opponents but no live adaptation
Terra Invicta
AI factions follow scripted priorities without adaptive player modelling
Teamfight Tactics leans a little harder on variance, though the gap is small.
Teamfight Tactics
Shop rolls and augment offerings swing lobbies
Terra Invicta
Alien incursion timing and random nation resistance rolls carry real unknowns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Teamfight Tactics
Econ curves, positioning, and comps are near-solved
Terra Invicta
Faction tech trees and Earth nation control routing form a deeply solvable layer
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.
