PortalvsStarDrive
Neither is simply harder - they are hard in different places. Portal demands more execution; StarDrive demands more reads.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
StarDrive
Optimization · Pure Optimization
A 4X space strategy game centered on modular ship design and empire optimization.
Portal leans Optimization (Pure Optimization); StarDrive leans Optimization (Pure Optimization).

Axis by axis
Execution4 vs 2
Portal leans clearly harder on execution.
Portal
Portal placement timing modest.
StarDrive
Real-time combat micro matters but never twitch-defines
Reads0 vs 2
StarDrive leans clearly harder on reads.
Portal
No adversary modeling player.
StarDrive
AI empires follow fixed strategies, not adaptation
Variance0 vs 2
StarDrive leans clearly harder on variance.
Portal
Deterministic chambers; no randomness.
StarDrive
Galaxy layout scripted-but-unknown until explored
Optimization8 vs 9
StarDrive leans a little harder on optimization, though the gap is small.
Portal
Pure puzzle-solving optimization.
StarDrive
Ship design, economy and expansion are the solvable 4X core
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.
