Its shocking how primitive most game engines are with audio processing. You get linear/inverse square falloff on volume over distance and perhaps reverb in some places and that's about it.
I also had a Vortex2 and it's not about requiring a high-end surround system, as I suspect even today there's still a significant amount of players with decent but not high-end audio. I was playing Quake3 with A3D before they patched it out with either basic stereo speakers or headphones and the placement was superb.

There's only so much you can do with just a left and right speaker and MAYBE a sub.
That said, it does seem like there's new interest in spatial audio, so we'll see. Maybe with some spatial audio headphones, and especially if they add head-tracking so that a sound to your left moves relative to your head (and stationary relative to your body) as you turn your head to face it.
I remember ages ago when it was new, my brother and I were shoveling snow for people to get pocket money to upgrade our PC. We settled on a Turtle Beach Montego II and I adored the thing.
Of course, it was short lived since the update in Windows driver model, and the bankruptcy of Aureal, ended things.
I actually got into retro computing a few years ago and got another Montego II off Ebay cheap and I have to say, the magic is still there.
Frankly, playing something like the original Unreal is my favorite example of a vintage experience that I can't replicate any other way - 3DFX Glide has an aesthetic and responsiveness that's hard to match, analog ps/2 keyboard and mouse with no latency, VGA CRT monitor, Aureal A3D audio with some headphones.
It's a singular experience that is impossible to replicate today. And I love it.
Aureal made the most unbeliveably amazing sound card, which use ray-tracing for sound, in hardware, to produce 3D sound like you are actually there. The sound engine knew the geometry of the space you were in, in your game.
I played the original Half-Life using this, and it was peak gaming.
