3. Silent hill 2

This is no doubt one of the richest horror games ever made. Featuring a tear-jerking plot, characters who act as if they are in another world, and some of the best horror done in a video game. There is a very good reason Silent Hill 2 appears on "Best games ever" and "Scariest video games ever" lists for a reason.

2. Deadly Premonition

even if you hate DP, or even if you love it. You MUST play it just for the experience of playing it. It's such an odd game, I mean, most of anything that comes out of Japan is odd (see Tetsuo: The Iron Man) but DP is odd in such an odd way that you want everyone to play. And it boasts one of the most original plots I've seen in years. And IGN didn't like it so you know it's good.

1. Deus Ex

Okay kiddies, put away Mass Effect and come play a real Sci-Fi RPG. Deus Ex is an incredible game, as it is one of the only games to offer choice and actually implement it well. Almost everything you do is observed by the game and everything is altered in response. You can change the way things play out by say, killing a certain character at a certain moment, or not killing them then. Deus Ex is incredibly deep, and as of now, boasts the best and most compelling plot I've ever seen in a video game.
