StingingVelvet: I was excited to see Bioshock Infinite come here for example, but am I paying $16 or whatever it was just to get a DRM free copy when I already have it? Nah. So that's probably stopping a lot of semi-modern releases from selling well.
GameRager: To me and others 16 bucks for the full game is a steal compared to release day prices....just saying. :\
^ I think StingingVelvet's point was (using the Bioshock example), B1 + B2 + BI games at their deepest discount are around £18 on GOG but the same games on Steam sold as a trilogy (Bioshock Collection) are only £9.99 (and include the Linux version of BI that GOG lacks). Whether a few people are willing to pay a whopping +80% premium just for DRM-Free or not,
A. It gets harder and harder to encourage newcomers to GOG when the first observation is
"Whoa, I don't mind paying a small premium for DRM-Free but +80% more is way too much for old games", and
B. It's not a good thing to habitualize people into accepting the "need" to pay almost double just to remove DRM when for +10 year old games, DRM-Free re-releases should really be the default without any special premium. I'm pretty sure this is half the reason why we keep stagnating with not seeing more mid 2000's to early 2010's era AAA's that are now as old today as Deus Ex, RTCW, System Shock 2, etc, were when GOG launched.
GameRager: Not to sound rude but then why do several people say here you need to DL the music because it was cut out due to licensing issues? Or did they put it back in(honestly asking here)?
The last time I looked, I'm sure the GOG version of Quake 1 does include the soundtrack in the form of 3x large files in the game folder that appear to be renamed ripped .ISO's (or BIN//CUE) of audio CD's. That's most of what makes up the "1.1GB" install size of the game on the game page. The game itself (inc expansions) fed into Quakespasm source port minus the soundtrack is only around 126MB, so most of what makes up the install size is the CD-Audio soundtrack ripped to uncompressed WAV format and stored in virtual optical disc container files.
