Day of the Tentacle
Day of the Tentacle is one of the top adventure games available when it comes to puzzles. When you consider that the player is required to control three people during three different time periods, with their actions from one impacting the other, it is even more astonishing that it is never obtuse or malicious. As Doc Brown would say, you have to think in four dimensions, and it is a credit to Tim Schafer, Dave Grossman, and the rest of the team that this never feels overpowering.
Day of the Tentacle, the game to which it is a successor, contains the entirety of LucasArts' prior adventure, Maniac Mansion, as an Easter Egg. It is still incredibly funny, gloriously weird, and timeless lovely. Although if the other point-and-click games on our list are fantastic, if you asked us to recommend one classic adventure for you to play, we would direct you here.
