Axis by axis
Execution6 vs 6
Even - both lean on execution about the same.
Reads6 vs 5
DayZ leans harder on reads: every survivor met may lie, ambush, or befriend
Variance7 vs 5
DayZ leans harder on variance: loot spawns and who you meet are unknowable
Optimization5 vs 6
SCUM leans harder on optimization: Deep metabolism and gear systems reward planning
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
