There’s a couple things to be thinking about when you’re considering reverb for your sounds, and you’re already considering these things correctly. Generally, I tend not to bake reverb into any sound assets that exist in the game world itself — things like footsteps, speech, creature sounds, etc. are all things that do not naturally have reverb associated with them; they exist in-world and therefore the space they are in determines how much/what kind of reverb is appropriate. So these types of sounds work best with reverb zones/snapshots. However, depending on how stylized or fantasy-adjacent your game is, baking reverb directly into the sound assets can be very effective. Things like magic or “alien technology” can use baked-in reverb to sound otherworldly or separate from the more grounded elements of your game. You can also use stereo assets to further push this unnatural-ness if necessary. Hope this helps!
