DayZThe Isle
Axis by axis
Execution6 vs 5
DayZ leans harder on execution: gunfights punish slow hands severely
Reads6 vs 6
Even - both lean on reads about the same.
Variance7 vs 5
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
