There are a couple of idiots in the comments who don't grasp what "up to 50% off" means.
Oh, I grasp what it means...I sorta want to call it misleading, I think technically it's not incorrect though, what they are claiming. GOG has some creative word-play (intentional?) and some janky discount mathematics going on depending on what you select, but lets take a look at GOG's press type release:
"Blaster Bundle - with 7 games up to 50% off, including the upgraded Star Wars X-Wing & TIE-Fighter series, and more Lucasfilm games brought back into the digital world from old CDs and dusty floppy disks."
If you don't buy the whole bundle, the best discount on a game (individually) is 25%. Discounts remained the same as getting each game individually, until you select the entire bundle, where then the bundle is really 37% off in total with 3 games out of 7 hitting 50% off. Eh, their press release claim is not incorrect, it's just a bit odd how it all "works".
"Saber Bundle - with
10 games at a flat 77% off, including Star Wars Battlefront II, Knights of the Old Republic I & II, the two Dark Forces games, and our two new completely new releases: Star Wars: Jedi Knight II: Jedi Outcast & Star Wars: Jedi Knight: Jedi Academy."
Ok, you only get 77% off if you get all the games...otherwise, if you remove one (or more) game(s), your discount drops to 40% - 46% ish.
I'd be curious if you get the bundle at 77% off if you own 1 or more of these games (I don't and I'm not taking one for the team...

). So again, technically, if you own none and get all the games, you get the full 77% off. Not sure what happens if you already own 1 or more (Do you get 77% on the remaining? do you only get somewhere in 40% - 46%?).
It's a bit weird that both bundles are structured differently. I think it's slightly misleading, but whatever.
Why am I even analyzing this? Am I an idiot? (I prefer the term moran...) When was I assimilated by ToasterNet and am I now turning into MysterD? I have too much time on my hands?....maybe I don't want to go back to playing Kane & Lynch: Dead Men....
