I've gotten over 40 but I would say I've never heard of most of them. You can get many of them just by being literal with the images.
ie. The word ON is hanging on to the side of a building, thus "Hang On" is the game.
ie. The word ARCH over III, thus "Archon 3" is the game
ie. There is a big burger with a clock face, thus "Burger Time" is the game
Of course not all of them are that easy and you really do have to know the games or the game icons (like Tron).
It's fun trying to solve the puzzles though
Thanks graylox!
