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

Optimization · Pure Optimization
A turn-based RPG where elemental surface interactions reward complete knowledge of combinatorial systems.

Optimization · Pure Optimization
A broken-system RPG where influence manipulation and prestige class chaining produce dominant power spikes.
Divinity: Original Sin leans Optimization (Pure Optimization); Knights of the Old Republic II: The Sith Lords 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.
Divinity: Original Sin
Turn-based combat requires zero twitch; positioning is deliberate
Knights of the Old Republic II: The Sith Lords
Pseudo-turn-based d20 system makes twitch irrelevant throughout
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Divinity: Original Sin
AI opponents use scripted priorities with no player modelling
Knights of the Old Republic II: The Sith Lords
Influence system uses scripted dialogue triggers, no adaptive opponent
Divinity: Original Sin leans a little harder on variance, though the gap is small.
Divinity: Original Sin
Elemental surface interactions contain hidden combinatorial space to discover
Knights of the Old Republic II: The Sith Lords
Influence thresholds and hidden stat distributions create first-play unknowns
Divinity: Original Sin leans a little harder on optimization, though the gap is small.
Divinity: Original Sin
Elemental chain combos and initiative manipulation are systemically solvable
Knights of the Old Republic II: The Sith Lords
Prestige class chaining and influence-stat transfer create near-broken optimization ceilings
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.
