Sam & Max: Season One
If you like adventure games, this is a great game.
The Dig is classic adventure game. Explore the environment, find items, add them to your inventory, talk to characters, solve puzzles.
Beautiful art, colorful characters, good voice acting(decent audio quality).
14 years old game and the graphics are still awesome. I like the movie and the game.
The Monkey Island Bounty Pack
The 'Monkey Island' serious is the single most influential adventure game series in the known Universe. It began life as an idea inside Ron Gilberts head as he rode upon Disney's Pirates of the Carribean ride, and it still lives today.
