I would like to see physically reflected stats, the leading example is that I want my characters body size to be altered by my strength.
When we all run around with the same body regardless of strength, I think its a little immersion breaking. When I have max strength, I want to look like it.
Other stats that have cosmetic effects would be for example: Agility effects muscle toning, ( in such a way a high strength and high agility characters looks different then just high strength, he is more toned, less body fat)
Other stats are more exact or, for the obvious few, completely undefinable.
The more "exact" would be endurance largely effecting the calf and thigh muscles, endurance can perhaps be represented other ways, but running and ergo leg condition is the simplest.
As for the undefinable, Intelligence is the most obvious. A magical glow is definately an option, but that seems like it should also be affected by what types of magic you are skilled with... but the larger problem, it would likely get distracting. Perhaps just a change in eyes could communicate the effect, a gentle glow in the iris starting at the 70% area, and ending with complete emmissive eyes at the maximums.
The above ideas would be best to be able to toggle off, and of course could easily be provided by modders after the fact, But I feel only the developer can deliver in perfect fashion on body type effects.
So there is my little thought, thoughts, support or violent assertions are all welcome.
