Try the Doom ones.
Total annihilation had an amazing score.. it was a young media giving talent a way to shine without first having to do a pilgrimage through some elder legends sweatshop.
I'll have to give them a shot, but admittedly the nostalgia is almost certainly a big reason I love the RA OST (and starcraft as well).
I didn't play enough doom to really love it in the same way.
Against all the evil that Hell can conjure, all the wickedness that mankind can produce, we will send unto them... only you. Rip and tear, until it is done.
And then I pay bills for eight hours.
