just installed shivering isles, i finished the main quest, mage's guild, fighers guild, arena and the dark brotherhood factions and beginning the thieves guild faction. i figured i'd play more oblivion after completing all the sidequests.
i'm not in the beginning at the part where you have to collect three crystals and guide a three-bunch through some 'traps'. great fun, i like these kinds of quests. reminds me of that quest for the dark brotherhood where you are 'trapped' in a house with some other people and you could manipulate people into doing and thinking things.
