Games that MUST be played.

Psychonauts.

No, it's not that you should play it because it's good, it's that you must buy it and play it or otherwise you're a dick. Anyone who has not bought that game should be ashamed of themselves, as it's philistines like you who are the reason why artful, fascinating and clever games aren't made.

Meh. It's just a 3D platformer, the story is more fun than the gameplay. 3D platformers are best left to consoles anyway and OP could just play it on a PS2.

Commander Keen

I don't know, Commander Keen is really brutal. Sure, it was one of the first big PC platformers, but I don't think it offers enough to a new gamer to be considered "Must Play."
And while I love my PC games, let's be honest: Mario is better. It can be hard too, sure, but CK can just be really fucking unfair.

Every S.T.A.L.K.E.R unit out there for the amazing atmosphere and Gameplay when either modded or patched.

World of Warcraft...cough.

Age of Empires.

Doom.

Metal Slug, or Mortal Kombat. Probably both.

Mario, original.

Battleships Forever. It's a top down tactical spaceship battle game that includes a shipmaker and room for custom sprites as well as weapons. Once you make your ship, you can modify HP for the hulls and the weapons along with weapon damage and range. You even have 4 different types of AI to choose from. The main game has a sandbox mode where you can spawn as many enemy, friendly, and player controlled ships as you want, whether they be massive or small, so you can have huge epic ship battles whenever you desire. Did I mention it's free? Get it now.

Oni, Command & Conqeur, Half Life, Shogo. Basically all the good old stuff.
Did I say you must play Oni?
Anyway, play Oni.

There's just some about Commander Keen that's so awesome though. I think most people should play it for about an hour, just to get an idea of what it's like. I played that game a lot when I was a kid, didn't make a whole lot of progress, but had a blast anyway.

Mass Effect 2 all the bloody way
