PvE is a widely used term to mean Player versus Environment. PvE is any kind
of player that plays through the storyline missions, killing monsters and
such. You can either have the option once you log in to create a PvE
character, or you can do the advanced option and do PvP. Everyone recommends
that new players play through PvE once with any character to get a feel of
the game itself.
