Metal Slug leans Execution (Practiced Mastery); Trackmania leans Execution (Pure Mechanics).
Metal SlugTrackmania
Axis by axis
Execution8 vs 10
Trackmania leans harder on execution: Pure input precision over deterministic tracks defines everything.
Reads0 vs 0
Even - both lean on reads about the same.
Variance1 vs 0
Metal Slug leans harder on variance: Spawns are nearly deterministic once a stage is learned
Optimization6 vs 7
Trackmania leans harder on optimization: Line optimization and shortcut discovery matter heavily.
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
