Planetside 2 rocks. I have been playing it since 2012 and still do to this day. CoD, Battlefield/front and other games feel weak in comparison. I met some of the best gaming buddies from PS2 as well. The teamwork, comradery and memories from this game alone make it worth while.
It's not a run & gun type game. It's about teamwork, communication and tactics. New players can get chewed up because they don't know the maps, vehicles or choke points etc. Don't let that discourage you. If you want to graduate from simple shooters like CoD or Battlefield, this is the game to do it with.
