There are only two versions as far as i am aware.What's the difference between that and the original?
V0 and V1 that is slightly more powerful, however there are few versions of the Tera Player and that includes: Light Edition, Standard Legacy Edition , Stealth Edition, and Ultra Stealth Edition that is harder to get and is completely black without any writing, truly beautiful.
I am not sure but some may be tunned a bit different as my Stealth Edition was a bit different than a Standard Legacy Edition.
CanJam is a good place for people to bring their Tera Player and try it with other owners.
All written above is IMHO.
