The Incredible Machine Megapack
GOG has The Incredible Machine on sale for $3.99 today. If you've ever
had a fascination with Rube Goldberg machines, you'll be sure to love this game: hamster wheels, darts, guns, bowling balls, and much, much more!
This is one of those classics that stands above its successors. Perhaps it's because the puzzles are designed to be solved any one of many ways (sort of like SpaceChem, another great game which coincidentally is also on sale today for $5.99
). Other games seem to have a "best" way solve their puzzles- e.g., you need to use such-and-such component to solve this puzzle efficiently. Sure, you can solve the puzzles differently, but why would you when the "answer" is so readily apparent?
Anyway, I digress. Go get this game and you will not be disappointed!
P.S. If it matters to you, GOG games are DRM-free!
P.P.S. The system specs say Windows XP or Vista... I don't know whether it works on Win7...
