Agree that there's not much here you couldn't do with another system, especially Cthulhu and/or EP. In that sense, it does seem to be a bit of a "sci-fi/horror heartbreaker."
That being said, I don't think it's history is necessarily that bad. Of course, when compared to something as unique as Eclipse Phase, sure. But on it's own it does its job, though it's nothing too groundbreaking. I do like the idea of the Cthonian Star approaching. In EP, the horror has already been released. Here it seems to be approaching or awakening.
Really though, my interest in it is just inspiration. Again, I probably won't ever run it, but I like collecting games that give me ideas and settings, not really so much for rules. I already have the rule sets I like (primarily EP and BRP). Most settings can be run in whatever system you really want to, anyway.
Anyway, it does bring up something I'm a big fan of: scavenging setting material and ideas from different games and supplements, and using them in my systems of choice.
Some examples:
I like the transhuman idea of switching bodies that is so prevalent in EP. I like it alot. Some of my players, though, are not as keen on the idea at all, but like other aspects of the setting. Meshing aspects of The Void with EP, or with CoC, might be a way to make a setting everyone wants to play in.
Recently, I found a print copy of Exquisite Replicas for very cheap. Will I ever run it as written, mechanics and all? No. But it is giving me some great ideas. I could give a long list of other games and supplements that I love, and will probably never run, at least not without converting them somehow (Kuro, Unkown Armies, Night's Black Agents, Summerland, Hunter: The Vigil come to mind, there are many more). As idea material, though, priceless.
Which is why I like raiding the bargain bins at gaming stores so much:)
