head to head
Quake asks more than Resistance 2, and the gap is execution.

Execution · Pure Mechanics
The original twitch FPS - movement tech and rockets define skill.

Execution · Pure Mechanics
Console shooter execution across scripted set pieces and once-massive human multiplayer.
Quake leans Execution (Pure Mechanics); Resistance 2 leans Execution (Pure Mechanics).
Quake leans clearly harder on execution.
Quake
Rocket aim and movement tech ceiling massive.
Resistance 2
Weapon handling and boss dodging demand console-shooter precision
Resistance 2 leans a little harder on reads, though the gap is small.
Quake
PvP duels involve real opponent modeling.
Resistance 2
60-player multiplayer rewarded reading humans; campaign Chimera don't adapt
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Quake
Item timing deterministic once learned.
Resistance 2
Campaign encounters are set pieces
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Quake
Map control and item routes solvable.
Resistance 2
Exotic weapon choice and class co-op roles add planning
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.
