Some free games to play include "Planetside 2" and "Defense of the Ancients 2." Some other free games include "Hearthstone: Heroes of Warcraft" and "Star Wars: The Old Republic."
"Planetside 2" is described as an epic first-person shooter. There are in-game purchases that users can invest in to improve the gaming experience, but players can still do well in the massive battlefield with just the default starting gear.
Another free game that players can enjoy is "Defense of the Ancients 2." This game's universe originated from a modification of "World of Warcraft 3," and since the first "Defense of the Ancients" game, the second has moved on to become its own entity, featuring its own lore and evolving world. It is a top-down arena battler that is always active, and the game features a professional gaming league that offers multi-million dollar prizes for serious players.
For players who prefer role-playing games, there is "Path of Exile." This is a hack-and-slash role-playing game that is reminiscent of "Diablo" and other similar classics. There is a complicated skill-progression tree and many hidden depths that players can discover after playing the game for a while. This game does not have a real money auction house, like in "Diablo III."
