head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Variance · Pure Chaos
The original board-game party romp where dice and Chance Time happily overrule whoever played best.

Variance · Pure Chaos
The shrunken handheld party where touchscreen minigames feed the usual dice-driven chaos.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Party
Stick-rotating and button minigames test hands briefly.
Mario Party DS
Touch and mic minigames test handheld dexterity.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Party
Mild rivalry calls in versus minigames.
Mario Party DS
Hex placement lightly targets rivals.

Mario Party
Dice rolls and chance time decide most boards.
Mario Party DS
Dice and hex RNG dominate the tiny boards.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
