How No Man’s Sky is opening up a once-niche genre to a new breed of space jockeys. If you sit Hello Games' indie title next to Star Citizen, it somehow feels more ambitious than Roberts’ offering, if only in terms of a very simple distinction: No Man’s Sky is targeting mainstream audiences.
Put simply, the space simulator isn’t a mainstream genre. Hell, the term ‘simulator’ is synonymous with a high barrier of entry, steep learning curve, and games from the genre are aimed at a technically minded player base looking to experience what it feels like to fly a jet. Pilot a chopper. Control a submarine. Launch into space.
