@Encha: I think he knows that.
@Gren: Sure, although it does not make a big difference in filesize, because the sound-effects are rather short anyway, but if you would combine the task of recoding them with the task of improving the quality of the samples that would be GREAT !
I say: Go Ahead Doing That !
I would suggest to use max 128 VBR oggs for the soundsamples. Please do use VBR, to have the stuff perfect, with no need to recode this ever again & look also @ the volume level, maybe some of the samples could use higher or lower volume, although we can adjust this via the game-engine also...
Great to hear, that you have not forgotten 'Return Journey', but I did never think that. An artist needs his time, so take the time needed to make stuff good.
