What kind of sounds do you use?

VesaN

Hi, we are planning on building a high quality sound asset library with CC0-license for indie developers. 

Your help would be very much appreciated by answering a few simple questions. It'll ease our pipeline getting to know any needs of the community.

1. First, what type(s) of sounds or soundscapes do you prioritize when developing video games?
2. Second, what kind of naming conventions would you like the sound assets to have?
3. Third, what sound formats does video game engines usually support?

Other comments?

Thanks for your help and time in advance!
