You can always defeat an army with your party of three. You can suffer from poison, blindness etc. Your legs stay completely unharmed even if you walk through a pool of lava or a bed of pins. The final boss always happen to escape death each time you fight it. New characters who join you always have good stats even though they've never fought before.
Robots eat, sleep, use potions etc.
You can fight in hundreds of battles, but you don't actually become any more powerful before you reach the next level. Monsters come out of nowhere as you walk around, but nothing will touch you if you stand still. Monsters carry money. You can attack something with a sword without having to run up to them first. You can punch a hedgehog with bare fists and suffer from no ill effects.
