"You can't do that much with 512MB [of RAM on a console], so that constrains a lot of your game design," said Roberts. "If I'm building a PC game, I'm going 'Yeah, you need 4GB on your machine.' Of course you're not going to get all 4GB because Windows is a hungry beast, but you're getting a lot more than 512MB so it kinds of open up what you can do, what you can fit in memory at the same time, and it changes your level of ambition."
That doesn't mean the game will necessarily be limited to PC, though. Developer Cloud Imperium set up a poll recently for further stretch goals to include in its fundraiser, with options of support for Mac and Linux. As it stands, 19 percent of voters want Linux support, with Mac on 8 percent. Both are way behind the likes of "tactical command mode on capital ships" (37 percent), "more star systems in Star Citizen" (39 percent), and more flyable ship classes (41 percent). If I were you, Mac users, I wouldn't hold my breath.
