I tried it last night....a little. Very nice, so far. I got hit and almost jumped out of my chair. Can I suggest you include a read-me listing what sounds are modified.
Also, I use "perfect map textures", with your sound and effects mod. Noticed when enabling the effects mod after perfect map textures, I get the warning, common files are changed, I click yes and it enables. This is also the case if I enable effects 1st, then perfect map textures. Is there a correct order to enable or doesn't it matter?
Are these final versions, or are you still working on them? They are really very nice, thank you.
