Pokemon Stadium 2
Human PvP cups reward prediction; AI cups are mappable
Risk: Global Domination
Human diplomacy, truces and betrayal timing cannot be solved
Risk: Global Domination leans a little harder on variance, though the gap is small.
Pokemon Stadium 2
Accuracy rolls, crits, rental rosters add randomness
Risk: Global Domination
Dice rolls swing battles and mission cards hide information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Pokemon Stadium 2
Team building, movesets, type matchups are solvable
Risk: Global Domination
Continent bonuses, troop math and border control are calculable
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.
