I love point and click adventures, Some of the best are Day of the Tentacle, Secret of Monkey Island I and II (there are special editions with improved graphics), Curse of Monkey Island. Grim Fandango is very good. My favourite is Indiana Jones and Fate of Antlantis - in one third of a game you have choice to go muscle, brain or teamwork, if you gonna play this game save your progress there, you can replay after you reach Atlantis, all three ways are diffrent and make a new gane. Game has CD edition with voiceover.
And last but not least there are Sierra games (Space Quest series, Quest for Gllory etc.). Enjoy playing!
