Sam & Max Hit the Road's visual style is the same cartoonish, pixelated look and feel that you might expect from a side-scrolling point-and-click adventure released in 1993. While the characters aren't quite as... abstract, as those seen in the original Monkey Island or Maniac Mansion, they aren't quite as smooth and clean looking as similar titles found later that decade. Quite frankly though, it's that look that adds a lot of the nostalgia to the game.
As for newer fans of the duo who came to know the crazed rabbit and his dog of a partner from Telltale's more recent titles, I feel like the graphics are still good enough to truly enjoy the crazy world that Sam and Max inhabit. Don't expect the whiz-bang, high-end 3D graphics of the Save the World series, but don't go into this game expecting something on the level of old-school Atari games either.
As for Sam & Max Hit the Road's audio features, it sounds like all of the original sound clips, music and voices are in play and nothing appears to be altered from the original release of the game. While I can't fully confirm this since it had been several years before this review that I had a chance to play this title, the music felt right and the voices were definitely that of Bill Farmer (Sam) and Nick Jameson (Max), whose banter is what really helped to define the crazed partnership these freelance police officers have.
