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

Optimization · Mind & Math
A full-loot sandbox where open-world PvP reads and economic optimisation are equally essential to survive.

Optimization · Grand Arena
Asymmetric sci-fi RTS where tiberium economy management and faction counter-play are the decisive layers.
Albion Online leans Optimization (Mind & Math); Command & Conquer: Tiberian Sun leans Optimization (Grand Arena).
Command & Conquer: Tiberian Sun leans a little harder on execution, though the gap is small.
Albion Online
Skill shot landing and kiting demand real mechanical precision
Command & Conquer: Tiberian Sun
Stealth unit deployment and artillery positioning need precise timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Albion Online
Full-loot open-world PvP means every encounter reads real opponents
Command & Conquer: Tiberian Sun
NOD vs GDI asymmetry means opponent strategy must be predicted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Albion Online
Dungeon mob behaviour adds variance but converges with knowledge
Command & Conquer: Tiberian Sun
Tiberium field growth and map elevation create meaningful uncertainty
Albion Online leans a little harder on optimization, though the gap is small.
Albion Online
Gear loadout, fame farming routes, and market arbitrage are all solvable
Command & Conquer: Tiberian Sun
Harvester routing and unit counter choices are deeply 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.
