Guild Wars 2

.. but i was wondering if the game is worth coming back for? I mean how is the pvp and everything? The game in general?

When you left?
PvP didn’t change much have a long time, last significant change was the introduction of the reward tracks.
It is pretty much up to you to try out and see if you like how the game is now, there is no fee to play it anyway

Population is good, plenty of fights in PvP/WvW and things to do in PvE. Still having fun close to 2 years in. You have already paid for the game so there is no price to logging in and taking a look for yourself. Only cost to you is the download time and client update if you are using a bandwidth restricted connection. Good gaming to you!
