Entropia Universe is a free-to-play massively multiplayer online role-playing game (MMORPG) set in the far future, where dangers, wonders and opportunities lie behind every corner. The game world is divided into multiple planets that the players can visit, each with their own theme. All the planets share the same game mechanics, with only slight variations. Besides a skill tree, there is also a profession system in place. Both can be used to gauge how efficient players are at what they are doing. A skill is improved by doing an activity related to it, for example the Rifle skill goes up when two-handed ranged weapons are used in combat, the Evade skill depends strictly on how many times the player avatar is hit by monsters in melee, while Mining is improved by extracting resources from the ground. Professions are, to put it simply, the sum of all skills tied to it, however certain skills can influence a profession more than the others. Once a set amount of skill points is reached, the player gets a better rank; being better at a profession is also shown via ranks and levels. There is no level cap in this game, but even so it's impossible to reach a 100% success rate.
