YaGramps: I'm aware of what Galaxy is. My question is whether it must be running to access BFII's online servers, or if online play will work without it.
Well sorry, but then you don't really know what Galaxy is, really. It doesn't do anything more than being the shop interface [just a browser for the actual website], it lists your installed games, it has rather rudimentary chat, and really, is mainly used to automate updating and installing your games for you. It's got an overlay for limited functions ingame as well, namely the chat I guess, but that does work on very few games only. Oh yeah, it can auto-upload your savegames to a cloud after playing if you fancy that, too, in case you have multiple PCs or want off-site backups for some reason. Galaxy really doesn't do anything -with- the games themselves though, other than install, update, and uninstall.
If it did, the games would actually
require Galaxy to work as advertised, and that's the whole point of GoG saying "no" to DRM and anything like it - you just download the game setup, double click it anywhere, any time, and you're done and set. No keys, no licenses, no limits, no accounts (other than for initial purchase), no logins, no required additional software. The fact that Galaxy is completely optional should be indication enough - you're fine without it, really, for when you wanna go the barebones route of having only the games installed and nothing more, and are taking care of updates manually. Or don't want updates at all! That's an option, too.
Galaxy is pretty handy none the less, for keeping your games updated.
But it's not such a mandatory overlord as Steam is.
