Gamorium's take

High-speed bike control and combat timing over memorised courses.
the cheat-test profile
Each axis is rated on its own - how far one cheat would trivialize the game here. They don't trade off; low on all four means the game is an experience, not a contest.
cheat: Aimbot - perfect inputs
High-speed steering plus melee timing against rival riders
cheat: Out-predict an adaptive opponent
AI riders follow patterns, not adaptive minds
cheat: See what's hidden / map the RNG
Traffic and rival behaviour inject mild chaos
cheat: A perfect solver / coach
Bike upgrades and track knowledge compound across the career
Each axis is named by the cheat that would break the game along it. Execution is the hands. Reads is out-thinking an adaptive opponent. Variance is hidden information & RNG. Optimization is the solvable systems layer. A game's region is the top one or two axes.
These four aren't one rating split four ways - they're independent 0-10 questions. A 9 on one axis takes nothing from the others, and a game low on all four isn't missing data: it's telling you there's no skill here to cheat.
The basis is how the majority actually plays this game - not a niche mode or a personal run. For a game with very different modes (a story campaign versus ranked multiplayer), that's the version most people mean.
Ranked by shared genre first, then by how closely the cheat-test profile matches - a cross-genre tag means a pick matched on skill profile alone.
