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

Optimization · Pure Optimization
A space tower-defense game solved by optimal module placement under timed pressure.

Optimization · Pure Optimization
A cover-based looter shooter where the spreadsheet of gear builds outweighs the gunplay.
Space Run: Fast and Safe Delivery leans Optimization (Pure Optimization); Tom Clancy's The Division leans Optimization (Pure Optimization).

Space Run: Fast and Safe Delivery
Real-time placement under pressure adds mild twitch
Tom Clancy's The Division
Cover shooting matters but bullet-sponge TTK softens aim skill
Tom Clancy's The Division leans a little harder on reads, though the gap is small.
Space Run: Fast and Safe Delivery
Enemy waves are scripted, not adapting to you
Tom Clancy's The Division
Dark Zone PvP adds real human betrayal and prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Space Run: Fast and Safe Delivery
Wave compositions and timing add bounded surprises
Tom Clancy's The Division
Loot rolls gate power; drops are dice
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Optimal weapon placement and resource use win runs
