Mw2 multiplayer. It's very addictive. I just can't stop. Most games for me I play for a few months like non stop and then don't play videogames until I get a new one. But I cant stop!
I would have to go with RDR (Red Dead Redemption) I can play it for hours hunting animals and hunting criminals it's really fun i have it for XBox 360 it's a great game i recommend it.
Assassins Creed 2. After I beat the game for the first time, I kept coming back to it to try and get all of the achievements... which I eventually did.
My favorite game is Assassin's Creed. I can play it for hours but the most addictive game for me is pacman, Surprised or shocked? But it was really addictive when i was child i was crazy for it.
Mine is Borderlands, Everyone Edits, Halo Reach, Max Payne, and The Godfather 1. I simply love those games. But Borderlands gets repetitive after you beat it. LITERALLY after you beat the game you have the option to beat the game AGAIN just with all of your skills and equipment. And everything has a different name. Not much different. But Everyone Edits. Pure awesomeness I'd say. Completely non repetitive but makes me angry at times. Especially those certain jumps where you have to jump to a cube that is right above your head and your suppose to time the jump perfectly >.> Just angers me. Really does. Halo reach just has an amazing campaign gameplay. Good looking achievement system. Multiplayer is awesome. And the armor CR system is incredible. Max Payne was the very first game I played in my life. I played it at 5. The storyline is riveting. The character is always talking in well thought out metaphors. The graphic novel is amazing. And the combat gameplay is so addicting and fun. Did I mention the game was made in 2001 I believe. Amazing game. You guys have to buy it. And the Godfather is an amazing game. The storyline is classic. The gameplay is sold and pretty unique. And the weapon system is amazing! Reminds me of Grand Theft Auto a bit. That's my list.
