Sam and Max are adventure games. Each one is like around 4 or so hours long depending on your skill with puzzle solving in these games. The first two seasons are point and click yeah but this new season (as far as the ps3 goes) the controls had to be adjusted so it's more you walk around and interact with things and use items that you have.
Sam and Max has a knack for getting better and better with each episode. Season One is still really amazing but if you want to give the new season a try don't feel put off because it's really easy to get into even for newcomers. You won't need to know any story stuff from the first two seasons as they've made it so that's not necessary. These first three episodes of the new season has been some of the best Sam and Max yet.
