The other day I was reading about the solar system. I can't believe how large it is, and how most of the graphical representations of it size are not to scale. Every poster I have ever seen titled "Our Solar System" is a lie.
Never tried that game. But from what I see in the screen shots, X3 seems to use tons more polygons with much more detailed textures. Assume they're similar, I wonder how much CPU power you'd need if you're battling thousands of space ships at once. Something Sins handle pretty well with their low poly models.
I have to buy a new computer. Gaming on the imac is terrible, especially when itunes is rolling, so I'm building a dedicated gaming box. Some of these space games have really nice scenery built in, almost as nice as EVE, although I prefer RTS for space titles.
