Control

Games where you direct something rather than play as it - a crowd, aircraft, a path. The challenge grows by giving you more to keep track of at once instead of demanding faster reactions.

Because mistakes are irreversible and arrive together. Aircraft can't stop, so a routing decision made twenty seconds ago is what causes the problem you're now trying to solve with three others incoming.

You steer a crowd through gates that multiply or subtract from it. The temptation is always to take the bigger multiplier, but a slightly worse gate you can actually reach is usually the right call.

Less than you would think. They test attention and planning rather than reaction speed, so the skill is in noticing a developing problem early rather than responding quickly once it arrives.
