head to head
Iron HarvestvsRust
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.
Iron Harvest
Optimization · Grand Arena
Diesel-punk CoH-style RTS with mechs and infantry cover.
Rust
Reads · Grand Arena
A multiplayer survival sandbox where human adversaries make every base a target.
Iron Harvest leans Optimization (Grand Arena); Rust leans Reads (Grand Arena).
Iron HarvestRust
Axis by axis
Execution6 vs 6
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Iron Harvest
squad micro and cover
Rust
Aim and recoil control crucial in PvP encounters.
Reads6 vs 7
Rust leans a little harder on reads, though the gap is small.
Iron Harvest
MP flanks vs humans
Rust
Human raiders and roamers adapt to your patterns constantly.

Iron Harvest
fog of war

Iron Harvest
build orders and unit comps
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.
