Supreme Commander leans clearly harder on execution.
Cossacks 3
unit micromanagement under real-time pressure
Supreme Commander
Massive APM demands across strategic-zoom battlefields
Cossacks 3 leans a little harder on reads, though the gap is small.
Cossacks 3
human opponents bluff builds and attacks
Supreme Commander
PvP hinges on scouting and countering opponent commitments
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cossacks 3
minor combat outcome randomness
Supreme Commander
Deterministic engine; only unscouted intel
Cossacks 3 leans a little harder on optimization, though the gap is small.
Cossacks 3
massive army economy and tech optimization
Supreme Commander
Streaming economy and build-order efficiency are the backbone
