Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.

Optimization · Pure Optimization
Planning quiet routes through guarded spaces using light and sound as solvable systems.
Fallout: New Vegas leans Optimization (Pure Optimization); Thief Gold leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Shooter inputs with VATS assist
Thief Gold
Careful movement and timing past guards, but slow-paced
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Scripted factions and enemies
Thief Gold
Guard AI reacts to noise via fixed rules, never models you
Thief Gold leans clearly harder on variance.
Fallout: New Vegas
Some loot and crit RNG
Thief Gold
Unscripted patrols and unknown layouts hide information first time through
Fallout: New Vegas leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Thief Gold
Route planning, light management and loot sweeps converge to mastery
