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

Optimization · Mind & Math
14-epoch RTS where economic scaling, epoch-rush timing, and civilization counter-picks span stone age to future war.

Reads · Grand Arena
A multiplayer survival sandbox where human adversaries make every base a target.
Empire Earth leans Optimization (Mind & Math); Rust leans Reads (Grand Arena).
Rust leans a little harder on execution, though the gap is small.
Empire Earth
Epoch-spanning army micro and hero management need consistent attention
Rust
Aim and recoil control crucial in PvP encounters.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Empire Earth
Opponent epoch rush and civilization bonuses must be predicted
Rust
Human raiders and roamers adapt to your patterns constantly.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Empire Earth
Map resource distribution adds uncertainty at start; converges quickly
Rust
Loot and resource spawns add modest randomness.
Empire Earth leans a little harder on optimization, though the gap is small.
Empire Earth
Epoch advancement timing and citizen allocation are near-optimally solvable
Rust
Base design, farming, and raid prep dominate strategy.
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.
