Descent3 VS dxx-rebirth

I don't know how much Descent 3 shares with the original in terms of AI code, but Descent 3 seems to give NPCs a dynamic list of goals that's initialized based on their class ("stalker", "evader", etc.).[1] Each goal has a priority/weight, and criteria that will cause the goal to be enabled or not. Some of the goal enablers are straightforward, but others look more like state machine "emotion" states - fear, curiousity, etc.[2]

Seems complex enough to meet the description on the box for the original Descent.

And that's the first level of Descent. :) I literally just started a brand-new game yesterday of Descent. DX-Rebirth.

Find a remake of the game ported to a modern engine. https://www.dxx-rebirth.com/ appears to be a port of Descent 1 and 2 to the Source engine. It won't help with you running the 3DFX version, of course, but this might actually be better?

I loved this game. You can still play it with DXX Rebirth

I would look at DXX rebirth, https://www.dxx-rebirth.com even if you just want to add the expansions to your steam version, you should be able to use its instructions to add the levels to your version.

Descent 2 - so long since I last played any Descent game I forgot how the experience was, but hey there's a source port!

Or if you still want to play the originals, the DXX Rebirth mods also make it easy to play on modern computers!
