most people here will not try to say that our projects really warrent such quality and are still verymuch of the mind that we are trying to save space here and there. I do not believe that outside of argh any of us see our projects as that high a quality. to justify going in and collecting something like a 128 quality audio.
So, basically until I finally make P.U.R.E. look like CryEngine, I should not have decent audio, even though OTA had decent audio? Smoth, don't defeat yourself by being so perfectionist... if music makes the experience more fun, ship it with music. IMO, it certainly does. The extra 50MB to include a few cute, Gundam-themed Japanese pop songs or whatever you think would be suitable is nothing, and music adds a lot.
And if your game weighs in at 200MB and you're still not using DDS, that's why. I have a lot more content in P.U.R.E. / World Builder: 350+ models and still growing, and the two content modules are 156 MB uncompressed (yes, that includes DDS DXT5 normalmaps for a fairly large percentage of the objects now). It only rises to the hundreds-of-megs levels because of maps.
And the people who moan about 50MB downloads aren't the people who are generally interested in buying the game, frankly. 200MB is nothing by today's standards.
