Last week, Steam introduced a new feature: “Early Access”
What is Early Access?
Get immediate access to games that are being developed with the community’s involvement. These are games that evolve as you play them, as you give feedback, and as the developers update and add content.
We like to think of games and game development as services that grow and evolve with the involvement of customers and the community. There have been a number of prominent titles that have embraced this model of development recently and found a lot of value in the process. We like to support and encourage developers who want to ship early, involve customers, and build lasting relationships that help everyone make better games.
You can now play to StarForge through “Early Access” programm.
