As a matter of fact, I did try using my sounds in a game, and I found them to be packaged in the most convenient way for me. Not only have I used my sounds - packaged in sausage files - in a game, but I also go through the effort of sausaging the files for sound libraries I buy that come with one sound variation per file.
Rarely, very rarely, do I need each sound variation in its own file for my daily work. Throughout this year, the only times I needed the files to be separate were in two very specific instances where I had to batch render a bunch randomized layers. But I digress.
I'm not familiar with the entire process of solo deving and publishing, I’ve never done it myself, but I assumed that people would be comfortable with using specialized tools for each part of the creative process. For example, Unity for implementation, Aseprite for visuals, and Reaper - maybe coupled with FMod - for sounds.
Again, I packaged and delivered these sounds in the way I would find optimal if I were searching for sounds online. When I published this same library in Airwiggles no one mentioned the packaging. But this might be because it is a sound designer-specific community.
Even here, I’ve seen few comments about the packaging, and none with your passion. Some people have contacted me to show their finished games using my sounds, and they haven’t mentioned any difficulty with using these.
I’m glad you’re satisfied with the quality of the content. I’ll try to provide a more amateur-friendly packaging option in the future.
