Best:
Mercenaries: Play Ground of Destruction:
Lets just say best game I've ever played on the original Xbox system. Ever. You kicked ass and could do almost anything, destroy any building, nuke a town, work for the US, Chinese, South Koreans, or the Russian Mafia, there were targets to capture or kill, money crates, weapon crates, FREE ROAM, you can explore anywhere and not be loyal to anyone. and just kick major ass no matter what playing style, and there was two different worlds you can explore from.
Mercenaries 2: This was a lower version of the first one, but still packed a great punch to anything. You could do almost everything you could in the first, with just more firepower. Excellent game series, unfortunately Pandemic shut down :(
Star Wars Battlefront 2: Pandemic mad this game, I can't explain how awesome this game was, spanned across every Star Wars (ALL 6) plus missions or just random battles you could be a clone or a jedi, or even be a droid or a sith. I love this game alittle more then the first to :X.
Halo 2: Some people WILL* disagree, everyone has their opinion, this was the best no matter if you played original on Xbox or the Xbox One Remastered version.
Battlefield Bad Company I: Loved more then COD.
Battlefield Bad Company II: Best Vietnam add-on then any game ever made hands down I don't care who you are.
Battlefield 1943: Best WWII game next to COD WAW.
Battlefield 3: Never loved an campaign and multiplayer more then this one, was really my favorite war game, after COD released their BO2 and on....
Battlefield 4: Upgraded graphics, with weapon physics and no hacking and you got yourself one of the most memorable games.
Call of Duty: Modern Warfare 2: I loved all the Modern Warfares, but this one stuck out the most, never wanted to play another Multiplayer game, even though it started to get hacked.
Metro 2033: Looking for apocalyptic craziness and absolute realism, only one difference, Russian Style, yes it is a russian themed game but you would never think it was this good and scary, at some points, first time playing needed my lights on....at 12 during the day.
Metro: Last Light: The sequal to an amazing first one.
Saints Row 2: Before maturity there was this, always one of my favorites.
Grand Theft Auto III: First GTA I've ever played, got hooked from there <3.
Grand Theft Auto Vice City: Another amazing GTA, but miami vice style.
Grand Theft Auto SA: Best installment ever, even out ranked GTA V in my book(on some standards)never seen a more versatile game. Literally do almost anything.
Grand Theft Auto IV (Lcpdfr only): Without GTA IV we wouldnt have LCPDFR, and let me tell you, I thank rock star for it, even though its demand and crash prone(alot) I will give it credit for bringing together a great group of people who all love to do the same thing. I thank it for it.
Grand Theft Auto V: Better then GTA IV and I cant wait to see what it has instore for the future of policing mods, and scripts, amen. Upgraded matching for online play brings a whole new sense of realism. Happy to play it and be here for it.
Command & Conquer: The First Decade (Yuri's Revenge, Generals): Like blowing up people and just seeing total destruction, play it, can't explain enough.
Fallout New Vegas: Never seen more accurateish game of what might life be like if the real thing ever happened, just wish they added a bike or something, lol.
Mafia II: Want to feel like you belong to a group of criminals, here you are.
Worst:
