Here's the Party Favor cost and time length of all of the unlockable minigames:

-------------------------60 SECONDS----------------------

Astroid Belt (10 F)

Chemical Imbalance (1 F)

Fish Flingers (3 F)

Food Fight (20 F)

-------------------------90 SECONDS----------------------

Lights Out (15 F)

Natural Disaster (5 F)

Power Boating (5 F)

Scuba Driving (15 F)

Short Circuit (5 F)

Spinball (15 F)

-------------------------120+ SECONDS------------------------

Aeroplane Island (15 F) [3 players need to complete 4 laps, takes 120-150 seconds]

The save file I start All Decks with has all 4 of the 60 second games unlocked, and all of the 90 second games except Natural Disaster. I unlock that one and one of the 120 second games over the course of the run to minimize the average minigame length.
