I adore Homeworld, and games like Nexus are also on my short list of favorites, so when I saw the GOG community's enthusiasm for Hegemonia I was eager to try it out. The gameplay is fine and enjoyable, but to put it simply, I cannot handle seeing Mercury, Venus, Earth and Mars on the screen at the same time in what is supposed to be an actual view of actual space. I made it to mission 2, where it looked like Jupiter, Saturn, and their respective moons were going to collapse into each other at any second, before I had to give up. Given all the excellent games that get the scale of space right - Homeworld, Nexus, Independence War, just to name a few - I don't feel like there's much excuse for the games that get it wrong. The enormous scale is part of the wonder and joy of flying and fighting in space. (I hated Freelancer for this same reason, along with its horrible flight model.)
As I was playing this game, it really just made me want to play Nexus and Homeworld again. Even Conquest: Frontier Wars would be preferable in terms of simple verisimilitude.
