I wouldn't mind clearing a game by sneaking into the main villain's quarters and slipping some poison into this food. Would give the game a more RPG feel. I guess they didn't want to make a good scenario out of it.
I dunno- some quests every now and then involving minigames like that instead of combat seems a good idea for variety. It's just when the only choice is between 'Parley' and 'Fetch quests' that the game suffers.
I'm fine with mini-games, just not like parley. Now to get a better bargain from an npc by playing a card game, or having to stealth around in an enemy hideout? Those are fine.
