Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
An open sandbox where mastering crafting and building systems dominates over any physical skill.

Optimization · Pure Optimization
The expanded sequel adds desert and arctic piñatas to the garden-ecosystem puzzle.
Minecraft: Java Edition leans Optimization (Pure Optimization); Viva Piñata: Trouble in Paradise leans Optimization (Pure Optimization).
Minecraft: Java Edition leans a little harder on execution, though the gap is small.
Minecraft: Java Edition
barely relevant, building/PvP negligible for most
Viva Piñata: Trouble in Paradise
Same gentle gardening controls
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft: Java Edition
no adaptive opponent, sandbox play
Viva Piñata: Trouble in Paradise
Creature behavior is rule-based, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft: Java Edition
world gen and mob spawns randomized
Viva Piñata: Trouble in Paradise
New biome visitors still arrive with some chance
Minecraft: Java Edition leans a little harder on optimization, though the gap is small.
Minecraft: Java Edition
redstone, base/resource routing solvable systems
Viva Piñata: Trouble in Paradise
Expanded species web deepens the requirement-solving game
