Heya Volfan!
I figured I would help you out with the terminology as I am a different server, so I can’t lead you in the right way >.>
In GW2, we mainly have 3 game types; PvE, PvP and WvW.
PvE is your standard player vs environment, and includes world bosses, dungeons, living story, etc.
PvP is an arena in its own and runs by 5v5. You can pug up these parties or enter with your own premade party. (I also run a casual NA/OCX PvP guild with no requirements if you want to give it a shot. Nothing is expected of you in this guild)
WvWvW (WvW for short) is a giant battleground spread across 4 maps. (Press B in game for info on how your server is going this week). Each week, these points are reset and matchups are sometimes changed around, so you would be fighting different servers occasionally. WvW is very heavily community based and you can choose if you want to be a part of this community or not (http://borlis.org/ is your server’s website, and that isn’t just for WvW things. That’s your community). Hardly anything would be expected of you there, but it can keep you in the loop.
PvX isn’t a game type, but it refers to a type of guild. PvX guilds play more or all game types efficiently (meaning they know what they’re doing in all activities).
