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
A pausable tactics RPG where party build and tactic-slot planning win fights.

Optimization · Pure Optimization
A fantasy RTS-RPG hybrid solved through army composition and tactical planning.
Dragon Age: Origins leans Optimization (Pure Optimization); King Arthur II: The Role-Playing Wargame 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.
Dragon Age: Origins
Tactical pause combat, low input demand
King Arthur II: The Role-Playing Wargame
Real-time battles need control but never twitch precision
King Arthur II: The Role-Playing Wargame leans a little harder on reads, though the gap is small.
Dragon Age: Origins
Enemy AI is scripted
King Arthur II: The Role-Playing Wargame
Scripted campaign foes don't adapt to your habits
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Age: Origins
Hidden rolls and loot tables
King Arthur II: The Role-Playing Wargame
Battle rolls and morale add bounded randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Age: Origins
Tactics slots, builds, party synergy dominate
King Arthur II: The Role-Playing Wargame
Army composition, hero builds and battle planning decide wins
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.
