DayZZ1 Battle Royale
Axis by axis
Execution6 vs 7
Z1 Battle Royale leans harder on execution: Gunplay, bullet drop, and car control under pressure
Reads6 vs 6
Even - both lean on reads about the same.
Variance7 vs 6
DayZ leans harder on variance: loot spawns and who you meet are unknowable
Optimization5 vs 4
DayZ leans harder on optimization: map knowledge and survival routines compound
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
