Hello. I found an updated game description. It says:
Includes Even More Incredible Machine, The Incredible Machine 2 and 3, Contraptions and Even More Contraptions
So I redownloaded the pack. But unfortunately, TIM2 is missing. If you want to add this game (it's just the DOS version of TIM3), you should do it. Or just correct the description, becuase it's not 100% accurate.

Cool, thought I was the only one to notice it.

I only got this game through a friend's recommendation but it did made me worry for a minute that there was something wrong my side but I'm glad to have check this forum and see that I am not the only one.

Me too. The description listed 5 games and I only got 4 (based on the icons in the Start Menu.) Are 2 of the games combined onto one, or should I feel cheated?

From wikipedia

Thank you for the info. It's good to know that we're not missing out on any levels.

I still think GOG should change the description, though, because it is misleading.

Hmm yeah, even though 2 and 3 are just the DOS and Windows versions of the same game they should still have both if they say they have both.

And still no answer from GOG... :/

It's not a major deal, but the description is incorrect. Also, the DOS TIM2 does have utility as it will run on any platform DOSBox is available whereas the other TIMs require windows or an x86 system with wine.

If you look at how that's written, 2 and 3 are listed as a single game. It could... probably be worded better.

'The Incredible Machine 3 (contains all levels from The Incredible Machine 2)'
