Hmmm… lets see here: About 80% of PC Games fit on 1 650-700meg CD. SoF2 fit on 2CDs BUT the game was only 1.1gigs installed (less than a quarter of a 4.7gig DVD). Gabriel Knight (one of the largest PC games at 5-7 CDs) would use DVD but most well-designed games DO NOT need even 2 CDs! DVDing would be useful for advertising other forthcoming offerings (via interactive anims) by the same game company. Nevertheless, even with all the Speech, Music, Sfxs, textures, and main game data most common-sense packaged and designed games will not exceed 700megs installed! Even if they did they’d only fit on less than a quarter DVD. I should know: I package games and its funny to see the damn holes in the code! Soo much fluff and unoptimization its sick! So in all… DVD = Re-packagable Common-Sense Game minus all the advertising crap! Only large Adventure Games (ie. the QUEST series or Full Throttle 2) need apply.
