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.

Gunpowder-era Total War blending empire management with line battles.

Optimization · Pure Optimization
A turn-based tactics game testing positioning and squad optimization against aliens.
Empire: Total War leans Optimization (Pure Optimization); Spaceland: Sci-Fi Indie Tactics 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.
Empire: Total War
Real-time battle micro is modest
Spaceland: Sci-Fi Indie Tactics
Turn-based commands need no twitch input
Empire: Total War leans a little harder on reads, though the gap is small.
Empire: Total War
Multiplayer line-battle feints exist
Spaceland: Sci-Fi Indie Tactics
Alien enemies follow scripted AI, not adapting to you
Spaceland: Sci-Fi Indie Tactics leans a little harder on variance, though the gap is small.
Empire: Total War
Campaign AI and battle dice noise
Spaceland: Sci-Fi Indie Tactics
Hit chances and fog of war add measured randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Empire: Total War
Campaign economy and line-infantry tactics are mappable
Spaceland: Sci-Fi Indie Tactics
Positioning, ability use and squad planning win battles
