JudasIscariot: You can install the games just fine on an external disk and as many times as you like :)
ERISS: We at least can save here the installers (and bonuses);
but, when we install games, often even GOG games put some keys in registry of Windows, no?
so there could be some problems if we launch a game with another PC than the one with which we installed the game.
I mean, if we
install a game only
one time, on an external HD, then we use the HD to play with another pc.
Traduc':
Il n'y a pas de problème de clef de registre? à lancer un jeu d'un autre PC que celui avec lequel on a installé le jeu.
For Windows games, yes. DOS games should be free of all that registry nonsense :)
