So, which games are on GOG that have a complete OTHER game as part of the goodies? I purchased one today; "Close Combat 2: A Bridge Too Far" comes with the original "Close Combat" as a game goodie.

Let's hear what other games have this interesting type of goodie.

Games with Games made me think of games that have... well games in it.

Like you can play Maniac Mansion in DotT. Or Super Chicken Turbo Puncher in Doom³...

Whaaat? I didn't know that, what a pleasant surprise. I was kinda disappointed earlier today thinking that the first CC game is still missing, not knowing it is already there...

I guess they decided to add it as a free extra to CC2, if they couldn't get it reliably to work with Windows 10. Good thing I still have Windows 7.

I think it is now a freebie if you own any one of the CC games but I guess you already know that

You have to send a ticket in to get them to do it.

Same here. I thought of System Shock. And Prey.
