kbnrylaec: Some mods check timestamp to keep compatibility.
New GOG installers do not keep correct timestamps.
hm, that's a good point. haven't seen any issues with that myself but I can imagine that this might cause problems.
That's a general problem with galaxy though. Anybody following the galaxy development/feedback thread and noticed this problem ever being mentioned ?
It's probably not even that hard to fix.
personally I didn't perceive the new installers as notably slower. But your argument about the increased hdd usage does make sense. (while my innoextract modification avoids the intermediate copy, I don't think there is a way to avoid it when normally running the installers)
as for the installer size: that's the old argument between faster (de)compression [zlib] <=> better compression [lzma2].
I would very much favour smaller files as well, but apparently GOG rather chooses speed over size.
same reason our linux installers are stuck with using zip.
hopefully most games keep their game assets reasonably well compressed for better loading times so that the additional compression algorithm applied for distribution won't be that important.
