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

Optimization · Pure Optimization
A Victorian-era RPG where the magic-versus-tech split and schematic mastery reward deep system optimization.

Optimization · Pure Optimization
A turn-based RPG where elemental surface interactions reward complete knowledge of combinatorial systems.
Arcanum: Of Steamworks and Magick Obscura 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.
Arcanum: Of Steamworks and Magick Obscura
Real-time mode is optional; turn-based eliminates all twitch
Divinity: Original Sin
Turn-based combat requires zero twitch; positioning is deliberate
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Arcanum: Of Steamworks and Magick Obscura
All NPCs and factions follow scripted dialogue and combat routines
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.
Arcanum: Of Steamworks and Magick Obscura
Hidden technology diagrams and faction reaction thresholds create exploration 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.
Arcanum: Of Steamworks and Magick Obscura
Magic versus technology stat split and schematic discovery are deeply optimizable
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.
