Axis by axis

Nidhogg 2 leans harder on reads: Still a pure human mind-game duel
Variance1 vs 2
Super Smash Bros. leans harder on variance: Item spawns add randomness; tournament rules strip most of it.
Optimization3 vs 4
Super Smash Bros. leans harder on optimization: Stage positioning and percent-based kill setups are learnable.
