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

Optimization · Pure Optimization
Comedic point-and-click adventure of Guybrush Threepwood, hand-drawn at its peak.

Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Turn-based double battles, menus only
The Curse of Monkey Island
pointing and clicking only
Pokemon Colosseum leans a little harder on reads, though the gap is small.
Pokemon Colosseum
All opponents scripted; no PvP focus
The Curse of Monkey Island
no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Shadow Pokemon snag rolls and crits
The Curse of Monkey Island
puzzle solutions unknown on first play, then fixed
Pokemon Colosseum leans a little harder on optimization, though the gap is small.
Pokemon Colosseum
Double-battle synergy and purification planning dominate
The Curse of Monkey Island
inventory logic puzzles are fully solvable
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
