Planet Side 2 - Epic Game and Free to play
The game is on a epic scale and one of my all time favorite games ever. As the game has not been out the longest time Sony is still working on a metagame. Capturing land and the need to keep it vs ghost capping still needs to be worked on but all and all I have never seen a first person shooter on such a epic scale where you can play solo or as a team. The 3 factions could also use some balancing. VS by far currently have the advantage but I am sure with some time they will balance out the equation.
Graphics are also top notch. I would recommend to sony is working on the meta-game and balancing each team. Sony seems to currently balance by who complains the most vs actually look at the specs and advantages of each weapon and vehicle.
