transplants), and wonders can increase happiness (e.g. Immunity Chip, Ramayana). Wonders These can be built by any civilization who has acquired the technology to do so. They take a longer time to build than ordinary buildings or units of that age, but have a greater effect, and a cinematic is shown when the player builds one. The wonders usually affect the civilization as a whole (with exceptions, such as Galileo's Telescope which effectively doubles scientific production in the city which it is built), and can only be built by one civilization. As with previous games, wonders can go obsolete with technological advances; if someone researches "Age of Reason", the Stonehenge wonder no longer has any benefits. Generally, wonders of the future have a greater effect than wonders of the past. If a city containing a wonder is taken by another player, then ownership of the wonder and its benefits go to the conqueror. Victory conditions Apart from conquering all opponents, players can achieve victory by completing the Alien Life Project, which is triggered by the "wormhole sensor" wonder. After a wormhole probe is sent through the wormhole, an alien life lab and a series of upgrades must be built to achieve victory. A player can also win by converting all enemy cities on the map. The final option is to get the highest score by the year 3,000. Release Call to Power was one of the most anticipated strategy games of 1999. It was published by Activision for Windows in 1999.
