The advantage of Mac OS is, you need no installers. But GOG offers pkg installers now. ;-( With that installers it is impossible to choose the loacation of the app. The installers copy the game data to /Applications but my games are in /Games
How I install the games in an other folder (NOT /Applications) ? Or how I move the games after installing?
They use .pkg's!? That's news to me. What games have you encountered that use .pkg files?
Assuming that the games are still installed as .app bundles with all of their game data contained therein, I don't see why you couldn't just move it from /Applications to whatever location you please.
Woa, if it's true, that seems quite annoying.
Btw, when I read "dmg", I always think at "damage" lol.
.dmg files are basically virtual disk images files similar to .cue files and the like. Open up the .dmg, then copy over the .app file, and you're done.
.pkg files are annoying because they're packages with install scripts, which mean that a given program may put stuff in all manner of places. That's of course necessary if you're talking about something that installs system-level components like a disk repair or anti-virus program. It's annoying when it's something like a game.
