Why did Ape Escape need two analog sticks?
Ape Escape was the first game ever to require Sony's DualShock controller, the twin-stick pad that became the template for nearly every controller since. The division of labour is the whole design: the left stick moves Spike, and the right stick operates his gadgets, swinging the monkey net in whatever direction the player flicks. Catching a running animal with a separate hand, while your other hand runs, is the game. Remove a stick and you have removed the verb.
THE TWO COVERS
One hunt, two names
THE SCHEME
Convention, deliberately brokenTHE PROOF
The remake that lost a stickHistory ran the control experiment. In 2005 the PSP remake, Ape Escape: On the Loose, brought the game to a handheld with a single analog nub. The net had to be rethought around buttons, the finely tuned feel of the original went with the second stick, and the score gap is the receipt: the original holds a 90 on Metacritic, the remake a 66, with GameSpot's review lamenting exactly the lost control.
Read that way, Ape Escape is a hardware argument that happened to be a hit. Twin sticks are now so standard that the scheme reads as obvious, but in 1999 Sony Japan bet a flagship game on a peripheral many players did not yet own, and the bet is why the game exists in its final shape. The monkeys, after all, are not hard to outrun. They are hard to catch with one hand.
