Oh! Can’t believe I forgot, but you should also play Under a Killing Moon, and then when you’re done and completely in love with it, move on to The Pandora Directive, Tex Murphy: Overseer, and Tesla Effect. They’re a series of hilarious retro-sci-fi gumshoe detective comedy puzzle adventures. It’s like Maltese Falcon, Blade Runner, the X-Files, and Young Frankenstein got put in a blender. They’re amazing.
