Alright, well, there's some votes and some statements. Not counting NoCam, who completely regrets this and has informed me I've ruined his life, seems like everyone wants to incorporate some mechanics and keep the universe going. So, I'm going to keep going.
I spent last night reading through the RT book. It's (thankfully) very, very similar to the system in place. If everyone wants to read 400 odd pages, we'll put the full system in place and I'll have you pick skills. Honestly though, the homebrew system I have in place now seems sufficient to make things work - if we were sitting around a table top, the RT system would be better, but it's a little complicated via forum as I'm rolling for everyone. So, I'll go with majority rule on that one, but I'm personally going to suggest we leave most of that alone.
As this is going to get more involved now that we're past the giant rat dungeon, any actions you may want to perform that require a test (that isn't just trivial or combat related) will have the required skills made known before I roll for them - some of you suck in some areas and are strong in others, so it will help you guys not fail due to confusion.
I would, however, suggest you look at the combat actions if you want - they're on page 238, and work just fine with the existing system.
Secondly, my ship system came from the old old old RT 1st ed, suggestions from a friend who played Battlefleet Gothic, and from some googling as to how RT new ed. does it. It actually seems to line up pretty much exactly, which is unsurprising as it's much less home-brewed. So, if you're planning to take part in ship combat, take a look at that, or at least the movement and combat section. It starts on page 193.
You can ignore virtually everything else in the book, since it works pretty differently than how my pre-designed mechanics are - they're simpler, which, once again, I think is easier given the forum medium. I will detail those as they come up - wealth is due for an indepth explanation, for example, because right now you guys really have no incentive to actually try to make money or any real idea of how much you already have.
And just as a heads up, as I'm very new at this sort of thing, if you guys find the setting and adventure of FTL isn't quite what you hoped, I'm not against revisiting playing RT or something similar instead. I have some tricks up my sleeve to make this a pretty fun thing, but am new enough that I might not work them in well, or might do so in a way you guys don't consider to check out, since I'm pretty much the only one who knows how the whole universe works. It's very easy to keep things interesting in a universe people besides myself are familiar with.
Here's a link to the sourcebook. Thank NoCam for that.
