Wanted to give a little love (although it's not all
totally founded love) to the Ape Escape spin-offs...
In the PS2/PSP era (and a bit in the PS3 period,) they used the series as a 'mascot' foundation for a bunch of experiments and genre goofs that I thought at the time was a good use of the brand... I kind of wish they did more with them actually, as they could have really pushed experimental play with dual sticks and motion sensing and cameras and everything else available, IMO. Also, many of these games never left Japan. Still, they did some notable side-games with the monkeys.
PSP was the biggest beneficiary of Apes at the time (naturally so, as the handheld's success in Japan and manageable-yet-powerful/versatile specs let Japan Studios go wild in a golden age of the division.) In addition to the remake of the first game (which was a little misguided since it didn't have dual sticks, but it is what it is,) they made a racer called
Saru Get You: Pipo Saru Racer (neat idea of 'wheeler' apes with wheels attached to their feet like Kineticas and the ability to stretch/squash/2wheel, although it seems so slow!, two
Ape Academy minigame collections, a serialized RPG called
Ape Quest (which I thought was a great idea and had fun design but kind of petered out before getting great,) and an Ape Escape 3 companion game
SaruSaru Big Mission where you control a helmet instead of a character and platform by mindjacking apes to use their special abilities.
Ape Escape also toyed around with the EyeToy and PS Move, which was something I personally thought was a promising use of its kooky concepts and experimental spirit. (Yet never Ape Escape VR!)
EyeToy: Monkey Mania had 50 camera-based minigames for kids and parties, and
PlayStation Move: Ape Escape was kind of a rails-shooter/bopper with Ape Escape gadgets to toy with.
And then PS2 had its own additional Ape Escapes, including the two party-style minigame collection/quests (
Pumped and Primed and
Million Monkeys, only one of which left Japan,) as well as, of course, the quietly-named yet wildly conceived
Ape Escape 2001, a monkey-pants vacuuming game.
