I tried playing for a while also. The game is very deficient in many many areas.
For starters, the learning curve is quite steep. When you begin the game, there is little indication of how to navigate your way around. Once you've figured out the controls, you'll probably get yourself killed quickly as the enemies in the game are more than your match as soon as you go to a slightly hostile world. Killing things is a pain, and combat frankly is quite unexciting.
Also, once you've been to about 5 planets, you've been to them all. Scenery is decent in space, but still becomes boring after a few hours. If you like doing things over and over and seeing the same things over and over, this is your game.
Playing on Linux, I also got a few segfaults which ended my playing. The game is definitely buggy.
On the plus side, the game has pretty realistic physics which I tend to like. I think the devs have created a good framework for a potentially good game, but what it really needs is more developers to start creating content and fluidity throughout the game. Bug fixes are important too. Art designers would also make the game way better. And since the game is fully FOSS, any developer who wants to help out shouldn't have a problem.
LFS has only one use - teaching you how to build a distribution should you want to be the next Red Hat, SuSe, Gentoo, etc. It does not belong any where near a real Linux installation - server OR desktop.
Do you have any reasons why "it does not belong any where near a real Linux installation"? Gentoo is, perhaps, even worse than an Ubuntu distribution in many circumstances. Unless you really know what you are doing, you're very likely to break things on a Gentoo distro.
If you won't want to use Gentoo, then use Slackware and install everything from source yourself. That's the only thing better than using Gentoo. And even LFS is sissified in comparison.
Also I'm betting you've never installed LFS. If you know what you are doing, you have almost ultimate control over your system with LFS. I'm betting the reason most people don't run it as a server is because it would be way too much effort to learn how to build an entire operating system just to run a server. Oh and let me know if you can think of a reason why it's "sissified".
No spitting on the Bus! Thank you, The Mgt.
