hey there great people from GOG and fellow gamers!

i was wondering: any of you ever thought this?
i discovered that since after Galaxy has launched some more features have been added, and games which i already cleared and of which i own all the save files of now have achievements that they originally didn't have (when i played them).

so i thought, wouldn't be nice to unlock achievements and milestones i've already reached for the games that support them through GOG Galaxy? if you got savegames and galaxy cloudsynching and your own stats, it shouldn't be that difficult to unlock those you already got in former playthroughs, right?

i'd like to hear your opinions, happy holidays!

It's quite difficult, actually. Nigh on impossible even.

Even https://www.gog.com/wishlist/galaxy/offline_achievements is still at the 'in progress' stage.

is it though? it would be easy to deduce from save games the game data necessary to compile passively all the statistics about certain in-game progress.

i mean: if a game collects how many head shots you did or how many hours you played or how long you took to complete a stage, usually these info are stored in profiles saved alongside local stored game data, and these are usually the data which, once checked by true/false conditions, unlock given achievements.

also, lots of games just have achievements regarding explicit portion/chapters of gametime/story. if you saved at 3rd-to-last stage, you have all the achievements for first to 3rd-to-last stage completion, boom: unlocked at the moment of reading savegames from their file system location (e.g.: launching gog galaxy or game itself). that should apply in similar way to really any other possible gameplay action to get recognized by a trophy or similar.

it's a no brainer, but care to remind: an achievement is just a checkbox about something done while playing, after all. contributed to the query, thanks for pointing it out for me
