EVERYONE'S IDEAS ON

What would build up the ''thrill'' of a gameplay and make it last longer?

How to expand the selection of weapons and armor, so everyone's character could have as unique appearance as possible?
It would be a very unique feature in the game, ''how to quadruple - or more'', the existing number of weapons and armor...

The simplest methods, for best results (vast variety of craftable weapons&armor - smooth system performance)
Here are two of my ideas:

1.) Smithing (or/and Enchanting) should be upgraded with a few more ''perks'', like:
- COLOR CHOOSING (10 different colours)
- SIZE CHOOSING (s, m, l, xl)
- PAINT CHOOSING (different paintings-lines-marks on armour,...), (10 types and different 10 colours)
- APPEARANCE CHOOSING (brand neww armour, old..., worn, damaged,..., clean, dirty,... ), (10 different types...)

The selection should be VERSATILE, but also AS SIMPLE AS IT CAN BE, to run 1000 different characters at once, smoothly.

2.) Slower leveling... (makes the ''thrill'' to last longer)

Simplicity produce the best result

A system like ArenaNet's dye system would be alright, but I think it may be a bit late to introduce something as big as this, it's not a game-breaker for me if they don't because I wasn't expecting it in the first place.
TES armour usually kicks ass anyway.
