Since there are still many great games out there that I haven't played yet, this list isn't really in any particular order, but I have given it a lot of thought. So here it is:

10. The Halo Series: By far the best FPS games I have ever played. The story is amazing, the action is nonstop, and there's something about killing hordes of enemy aliens that makes you feel like a total badass.

9. The Super Smash Bros. Series: I have been playing this series ever since I was a child. Fighting with a whole bunch of Nintendo characters that you know and love was amazing. I prefer Melee over Brawl, but Brawl is still a good one.

8. Portal 1 and 2: While Portal was only a three hour game ( for most ) I absolutely love it. I still play the advanced chambers when I'm bored, and GLaDos has to be one of the best characters ever created.Portal 2 expands on the story created by the first one, bringing GLados back to life and having you do more experiments. These game are hilarious and always manages to keep you entertained.

7. Assassin's Creed 2: There is nothing about this game that isn't amazing. The story, conspiracy, and creative ways you could kill guards is simply great. One of the best and most memorable games I've ever played.

6. Metal Gear Solid 1: This is the first game i played on the PS1. Never before had I played a game where I had to sneak around, constantly avoiding enemy sight and having to be careful about leaving footprints in the snow. I loved the story and the crazy boss fights.

5. Batman Arkham Asylum: I am a hardcore Batman fan and this game was everything I expected it to be and more. Beating down and countering enemies like it was nothing was beast. Solving the riddles and the mystery behind Arkham Asylum was fun and interesting as well. Definitely a must play even if you're not much of a Batman fan.

4. Assassin's Creed Brotherhood: Awesome storyline that continues after AC 2, this game has a lot of mystery and puzzles that you have to solve. While the multiplayer takes a while to get used to, it is still very entertaining. Also, the execution streaks were a great addition to the combat.

3. Call of Duty Modern Warfare: One of the first FPS to get out of the whole overcrowded WW2 scene, MW brings excellent story, customizable weapons and great multiplayer. One of the best and most entertaining FPS out there.

2. Call of Duty Modern Warfare 2: Currently my favorite FPS game. The story is amazing since it involves the US getting invaded by Russian forces, and great multiplayer because of the many available killstreaks. The feeling you get when you Nuke everyone in the match is priceless.

1. Marvel Vs Capcom 2: The best fighting game ever created. I spent countless time and money playing this game. for several years, I would go and play this game in the arcade everyday after school with friends. It's the most memorable game I've ever played.
