As in previous games, there are many ways to achieve victory. The player can focus on scientific research and become the first to assemble and launch a spaceship and win the space race. The player can focus on a diplomatic victory that requires the support of other civilizations and city-states to the United Nations. In the new cultural system of civilization V, composed of “trees” of social policy, the cultural victory over the Brave New World Expansion Pack included the filling of five of the ten “trees” and the completion of the Utopia project (reminiscent of the secret project to Ascent Transcendence in Sid Meiers Alpha Centauri).  Reducing research costs: Meeting Civs Encounter with other civilizations that have explored a technology you don`t have will reduce the cost of this technology. It`s a reasonable mechanic, as if you see someone using a new invention, it becomes easier to discover for yourself. The more you know about the Civs who have studied something, the lower the cost of this technology will be. As you move towards education and scientific theory, other Civs are likely to explore military technologies at the lower end of the tech tree. You will be able to catch up faster in military technology thanks to this one, so meeting Civs on scouting and later with Caravels to explore the world (or when creating the World Congress) is important for the pace of your research.
G4TV there were 5 out of 5 and described it as a “fantastic strategy game based on rounds… In many ways… the best representation of the series and certainly the most accessible for new and old players “, added that the “diplomatic model is anemic” and describes the AI as “pretty average “.  IGN gave the game an “Outstanding 9.0,” said “This is the first civilization for PC that is worth the time to almost every person,” but also criticize the AI for being too aggressive and note that players who have played Civilization IV may miss the bourgeois and religious characteristics.  GameSpot praised the game`s addiction and said it was “another glittering example of turn-by-turn happiness that will keep you long beyond bedtime.”  Investments in research agreements are lost if they are broken. That`s why you should never go to war with your research partners if you can help him — because you lose both.
