This makes the encounters that much more intense, not to mention the fact that the confrontations are usually between more than two characters. However, instead of having to choose one or the other to start playing, you can actually switch between them at the flick of a button during gameplay. These heroes are actually called mercenaries, and you get to hire them whenever you have enough cash to unlock their powers. In essence, it is an online fighting game, which means that players get together and share a good beating, in order to compete for currency and experience, both of which can be used to acquire more heroes. Lost Saga is exactly that and it did a pretty good job at expanding its influence since it was released, because it managed to get from South Korea all over Asia and even to North America. However, it would be tons of fun if you could do this online, with more than one other player. Hence, whether it was arcade machines a few decades back or the state-of-the-art PlayStation 4 nowadays, everyone is up for a round of button mashing with Mortal Kombat or Guilty Gear. Fighting games have a long history of being popular, regardless of period or the platform they are released on.
