I feel like I have startover-itis. Sometimes when I'm playing I get an idea for a new character or a way new way to do things. Maybe I'm just being picky, or something about my current character just might stand out as odd or doesn't fit with how things should be. When you create characters that last a long time, do you take any steps to plan things ahead, what's the process like for creating someone you really like to play as?

*perfect build (no mistakes with leveling always +5 +5 +1)
*no quests ruined (no npc killing that I may need for a quest later even if it's just a side-quest)
*collecting a complete set of weapons and armour, (a collection in it's own right) for it, stored in my house.

so for me it's mostly about thinking about what I want to become statwise as a level 40, and make sure I pick race, birthsign, atributes and skills to suit it.
also I need to watch my leveling, pick skills that level not to much as mayors so I can manage the +5 boosts
for quests I use the wiki.. if I am thinking about killing an npc I always check if he/she is needed in a quest later BEFORE making that kill.
about the collecting gear, that takes little effort, just maintaining a sheat what I already have.. so I wont use up valueble inventory space for items I already have in my set.
(as it is impossible to remember it all on my own)

and when I feel something is missing for my char, anything, I try to downloand or make a mod, to fill that gap.
