MegaWorld
Menu-driven building with no physical demand
The Elder Scrolls V: Skyrim

MegaWorld
Open-market trading against players adds light prediction
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.

MegaWorld
Market swings carry some hidden information
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
The Elder Scrolls V: Skyrim leans a little harder on optimization, though the gap is small.
