Game doesn't seem to care about Load / Agility at all for player speed.

Red Potion doesn't last as long.

Duncan is taken from you automatically, and I think dumps their inventory into yours.

Screen is (obviously) smaller, you need to press select at the player screen to see stats.

Red pot can be drunk by anyone for speedboost, but will only heal that character.

Swordfight opponents have much less mobility, and don't get stuck as easily (the prison fight, the opponent can actually turn around).

The skeleton dies from one hit.

You can't stun-lock the boar with the staff from little john (but you do have a safe corner for wailing).

You can hit the water enemies while they aren't visible.

World bosses don't have HP totals.

Unlimited continues(?)

The codes might actually give all the required items.

?You can lose the mass battles as Robin Hood, win, and will end with 1 hp.
