I still think there should be a standard sound FX pack as well... especially since unlike with images, you have to have EVERY sound you're using, even the stock ones, in the mod directory if you have a Sounds directory under the mod directory
(I used to have all the SFX from MOO2, plus a few unused ones like a cool electric discharge that they threw into the sound file, extracted with something like LbxEx, but I can't find a working Version of that program (or maybe my MOO2 files are corrupted)... those would make a GREAT addition to SE4's sound library! Stellar converters away!
