Eve Echoes is a Mobile MMORPG. (Massive Multiplayer Online Role Playing Game)
Thousands of players can play together at the same time and there is no need to save your gameplay since all information is stored automatically on the servers of EVE Echoes.
Compared to other MMORPGs, EVE Echoes prides itself to be an open world sandbox. Meaning a player is not too restricted about what to do and what not to do. If you want to open a mining enterprise feel free to do so, if you want to be a pirate and make money off the backs of other players you are welcome to do so as well.
There is no strict end game in EVE Echoes as in, one sets their own goals by themselves. If your end goal is to be the strongest frigate fighter, you can do so. If it is to build the biggest corporation then do so. What you will be and what you want to do is up to you.
