head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Practiced Mastery
Scheduling and routing a fixed 72-hour clock through zombie-filled detours.

Optimization · Practiced Mastery
A rhythm-driven falling-block puzzler about building clears to the beat.
Dead Rising 2 leans Optimization (Practiced Mastery); Lumines Remastered leans Optimization (Practiced Mastery).
Lumines Remastered leans a little harder on execution, though the gap is small.
Dead Rising 2
Crowd-clearing combat needs competence, not twitch mastery
Lumines Remastered
fast block placement under time pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Rising 2
Zombies and psychopaths follow fixed behaviour
Lumines Remastered
no opponent, purely solo puzzle
Lumines Remastered leans a little harder on variance, though the gap is small.
Dead Rising 2
Survivor events are scripted-but-unknown on first runs
Lumines Remastered
random block sequences drive setups
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Rising 2
The 72-hour clock makes scheduling and routing the real game
Lumines Remastered
chain-building strategy and block-clearing timing
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.
