if i'm correct :
it's a repackaging :
- some games doesn't like the periods in the default path name (since gog.com has one ...)
- now games files are max 1.5GB (i guess it's for more compatibility)
- include a pdf reader (optional)
- some games using DOSBox , got the lastest version integrated
i surely i missed some points
anyway if a game works properly on your system , u don't need the new installer.
but of course u need the new installer , for future patches.
you made those all from hat right?
There were games which are 3 gigs and.. better love it, it your's for life. ^^
Future patches indeed but I would like to know if I should bother with it or just if i download a normal thing is itr the same and how come Stonekeep those 2 orcs are so hard?
Edit2: and with hard I mean, seems impossible
i guess some games have been patched too , so maybe some areas could be harder (i don't own stonekeep )
yeah there's the compatibility with win 8 too, it s quite logical after all.
and i forgot all installer have a digital signature (easy to check if the installer is corrupt or not)
