I haven't played SC for a while, I'll wait now until that 3.0 release at the end of the year.
I watched the presentation and I have to say, provided it runs well for players. I think CIG are way ahead of the curve compared to FD. That presentation was a great showcase. However, we have had showcases before that turned out pretty unplayable for quite a while, so lets hope CIG have learned from that.
The seamless nature, albeit in a smaller universe, is the best I've seen in a space game. To be able to do all of that, in that detail, is pretty mind blowing. But I'll need to be able to play like that for many hours (smoothly), to be able to say it works as we've seen it.
Star Citizen are pushing the boundaries. It may not be the scale of other games, but coming at it game-play wise, the scale is vastly bigger than we see in any of its competitors. Looks great. Its just a case of, will it run like that for the normal player. I certainly hope so.
Good job CIG.
