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!

I hate point and click adventure games, but I can suggest one that I actually enjoyed. It's Beneath a Steel Sky. I like it because it's set in a dsytopian future, and it's cyberpunk. It also had an interesting enough story that I played it, despite it being a p n' d. Of course, I had a walk thru, which took a lot of the frustration out of it, and allowed me to play it just for the story. Best of all, it's free on Gog.com! There's also a bunch of other p n' ds on there, so you'd probably want to check them out as well.
