Sam & Max! Don't get me wrong, I love the MI Series and bought them all, back in the days, but Max is my all-time favorite. He's so fluffy .... and cruel!
ToMI probably does a better job at appealing to the masses, but Sam&Max is the game of choice for every old-school, senseless-violence-loving adventurer.
Max: Does it involve wanton destruction?
Sam: We can only hope.
...
Sam: Who was that?
Max: I don't know, but if it weren't for the sheer carefree innocence of this carnival, I'd be breaking his kneecaps.
Sam: You're a demonic little imp, Max.
...
Max: Gosh, Sam, if 100 years of western civilization have to be destroyed just to provide a bunch of smelly quasi-human creatures with a safe haven for their disgusting lifestyles, then so be it!
