A lot of them have already been posted, but I compiled the list for personal use so won't bother with taking out the ones already mentioned.

These are 80, but I'm not sure if the single games with 10% (like Journey to the Center of the Earth) count, as that would put the count above 80.

Feel free to correct me if I messed up anything.

EDIT: And it seems like none of Ubisoft or Strategy First games have a discount pack deal.

adambiser: Is http://www.gog.com/game/dream_pinball_3d intended to be in a bundle? Right now it's a bundle of one...

adambiser: You're welcome. I'm slowly going through them all page-by-page to see what's there for the gogwiki page.

By the way, it's still a bundle of one, but no longer has a discount. (Same with Journey to the Center of the Earth.) Just making sure that's intended, too.

HypersomniacLive: You're very welcome.

Don't mean to be pushy, but maybe someone at GOG would like to have a look at some other things I pointed out here?

adambiser: Another misspelling:
http://www.gog.com/game/total_anihilation_commander_pack
"Total Anihilation games on GOG.com"

adambiser: Interstate '76+'82 doesn't appear to be a discounted bundle anymore...

Same with the King's Quest games...
adambiser: Did you intend to remove the discount on some bundles? (like the two mentioned here, there may be others)

If so, never mind me. :)
