So I played a bit of both Morrowind/Oblivion and now I'm restarting Oblivion after getting a feel for the game and shelving it for a bit. All I want to know is can I have 1 character do everything? That is, if I'm playing a spell caster and I, in effect, maximize his spellcasting abilities, can I then work on rogue abilites (blade/stealth/etc.) and maximize those as well before continuing to a warrior type build? Or must I realistically create a new character for each class type?
