korribenon: Well, that's fairly disappointing. That GOG doesn't keep the individual patches available for download is ridiculous. Seems like they are trying to force Galaxy on users. Poor decision, GOG.
It is a matter of storage space and maintenance . Next you will argue that 300Mb means nothing. Now take that and multiply it by the entire history of all available games. It is also a matter of being able to keep track of all of it. Much easier if it is now in 1 or 2 files instead of dozens. You can't have that level of maintenance and also the price you want. Pick one.
Having said that, it would be nice if they had a email notification or something when there are patches available for your owned games.
