other ( if you pick this weight what you think)
Would like the helmet-off-outside-tower idea (helmet would be transparent enough for face to be seen, nothing more). Referring to World of Warcraft in the options tab you can turn off the ability to see the helmet, etc... But the helmet should be transparent, to show that you're seeing through the helmet (via advanced technologies that should be available by then). Enemy players would not be able to see your face. Vica-versa.
