The question is, of all the TES games you played, which one satisfied your thief's needs the most, both aesthetically and from a practical perspective.

Considering every aspect related to this career: opportunities to roleplay, outfits, skills, city and buildings design, lockpicks, specific quests and NPC's, thieves guild questline, loot system and rewards for your effort, etc...

Gotta be Oblivion.Loved the Cowl.
