Exactly what you said!
It does sound just like the opening to a game. The first thing I thought of when listening was the opening video clip from StarCraft.
Ok now the song has really gotten underway, and yeah, I could destroy some serious space rocks to this =P. At 1:50 however I would prefer the progression of C, Eb, Low G, back up to C..but that would make a different song =P.
Now the song changes alot at 2:03. Interesting percussive work here, it's unique and still fits...I like it. You also seem to have some analog bass going on here, this part reminds me of just flying through space. After the synth comes in I'm feeling a little bit more energy and action, perhaps something is happening. And now with the voice-overs and lovely keyboard action...we are coming into the space station maybe just turned thrusteers off and a free floating to the station. After this we get some ambient crashes, we have landed!
SWEET song man! I love the overall feeling to this one, I especially think you've mastered ambience in the beginning and end of your songs.
Excellent! I was thinking about a new trilogy set utilizing this type of theme, much like what I did with Immortal Crossings, etc. I'm still feeling out some new grounds (<---Haha, pun) here with this type of style. Maybe I can also tweak this a tad. Again I was trying to keep it uncluttered. I really need a new keyboard, as I have some awesome ideas for main themes to my music, but no way to realize them!
