Mass Effect: Andromeda will have us exploring the Helius Cluster, deep in the Andromeda Galaxy, searching for 'Golden Worlds.' These 'Golden Worlds' are the strongest candidates for settlement or whose resources could bolster the Initiative's chances of long-term survival.
Resources help upgrade the Nexus and those upgrades help wake up more colonists from cryosleep.
In the video, there are seven planets detailed to be possible 'Golden Worlds.' It's unclear whether or not one of these seven worlds will be available as the one accessible world in the early access granted by EA Access and Origin Access.
Additionally, a gameplay video detailed planet exploration to feature over 100 planets, but only a handful of accessible planets.
In order for planets to be colonized, Pathfinders will have to pacify possible dangers on the planets, befriend the indigenous populations, and resolve environmental problems. The first step of colonizing a planet is setting up an outpost or Forward Station. Following that step, colonists can be woken up from cryosleep to continue the colonization process.
