One of the best things about any new Arcen title is the selection of Pablo Vega music that comes with it.
Even though the music isn't hooked up to the game yet, I've been listening to the two ingame suites and the title themes while I play. (And while I work, because I still have to earn a living while testing SBR.) I haven't been listening to the per-race music as much because a lot of it is already really familiar to me -- I'll probably add it to the mix in a few days to stretch out the variety a bit.
I loved the Stars Suite from the moment I started playing it, and it already has a permanent place on my coding playlist next to Neinzul Lullaby, Night Carousel, Hidden In The Dark, Rise And Shine, Stantonsburg, Henchman Elder, Black Market, ... *ahem*, I won't list all of it. Suffice to say that the 6+ hours in that playlist isn't enough.
Into The Black Hole... well, the meanest thing Chris has ever done to me was mentioning it in the changelog and then making me wait almost a full day (stupid timezones) before I got to hear it. The wait was worth it. That bit about two and a half minutes in... wow. Completely unexpected and completely appropriate.
In a way, I'm kind of glad the main theme music hasn't been hooked up yet. I'd probably be stuck at the main menu for three and a half minutes every time I start the game, which would severely impact my ability to playtest. (Bionic Dues did that to me. A lot. Something like 10% of my "playtime" in that game is listening to The Home That We Once Knew all the way through before I get into my giant robots to go kill other giant robots.)
Anyway, what I really wanted to talk about was the Krolin theme. There had better be creepy shadow beings in their backstory. And zombies. Maybe a giant squid monster or two. The Acutians won't know what hit them.
