head to head
StarCraft II: Wings of Liberty asks more than Tekken 8, and the gap is optimization.

Execution · Grand Arena
Real-time strategy where hands, reads, and build optimization all matter at the top.

Execution · Grand Arena
A 3D fighter where movement and mixup reads decide rounds.
StarCraft II: Wings of Liberty leans Execution (Grand Arena); Tekken 8 leans Execution (Grand Arena).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
StarCraft II: Wings of Liberty
APM, macro, micro-control under pressure
Tekken 8
Just-frame inputs and 3D movement punish sloppy hands.
Tekken 8 leans a little harder on reads, though the gap is small.
StarCraft II: Wings of Liberty
1v1 ladder vs adaptive humans modeling you
Tekken 8
Adaptive opponents mix lows, highs, and throws.
StarCraft II: Wings of Liberty leans a little harder on variance, though the gap is small.
StarCraft II: Wings of Liberty
map spawns minor; mostly known
Tekken 8
Negligible RNG in core matches.
StarCraft II: Wings of Liberty leans clearly harder on optimization.
StarCraft II: Wings of Liberty
build orders, economy curves heavily solved
Tekken 8
Frame data, punishes, and movelist depth.
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.
