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

Optimization · Pure Optimization
Optimizing city placement, social policies, and victory routing under randomized map unknowns.

Optimization · Pure Optimization
A turn-based RPG where elemental surface interactions reward complete knowledge of combinatorial systems.
Civilization V leans Optimization (Pure Optimization); Divinity: Original Sin 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.
Civilization V
UI actions need no precision; speed is not a factor
Divinity: Original Sin
Turn-based combat requires zero twitch; positioning is deliberate
Civilization V leans a little harder on reads, though the gap is small.
Civilization V
AI follows scripted personalities, not genuine player modelling
Divinity: Original Sin
AI opponents use scripted priorities with no player modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Civilization V
Random starts, barbarian spawns, and goody huts create hidden unknowns
Divinity: Original Sin
Elemental surface interactions contain hidden combinatorial space to discover
Divinity: Original Sin leans a little harder on optimization, though the gap is small.
Civilization V
Hex placement, social policies, and victory routing are fully solvable
Divinity: Original Sin
Elemental chain combos and initiative manipulation are systemically solvable
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.
