I'm going with just about any Metal Gear Solid game except for 5 lol.. but if I had to pick one, it's the original. Still one of the best games ever, and the story will have you hooked from beginning to end. If you skip cut scenes, you can probably beat it in like 4-5 hours. With cut scenes, it's maybe 8 or 9 hours. But if this is your first time playing, maybe add an hour or two. So that's my recommendation. What's yours?
