tried not to be too repetitive and instead of being my favorite games of all time i tried to vary it for genre's there so many games that i love it's not that easy to come up with a definite list. =P
Final Fantasy III/ VI : It's by far always the first thing that comes to mind both for it's inmense nostalgia factor, as well for it's timeless quality and scope, on perspective FFVI individual elements all make to me the perfect jrpg, there are aspects i dislike of other FF's however with Vi it's hard to find a fault, from the characters, to the combat, and the iconic scenes like the Opera, FFVI exudes a personality that is rare to find even today in modern games, for all the advancements in gaming, VI still holds as a staple of gaming perfection (at least for me)
Also Kefka.....
Zelda Ocarina of Time: One of the best examples of Adventure games out there, the story isn't particularly the best, however the game, aside from being called the best game in history, (which i disagree) is still one of the best experiences i can remember in gaming. The diversity in creatures, the way the world opens up to you, and gradually became something more organic and believable than other games at it's time, a beautiful aesthetic design woven into a intricate and fun gameplay made ocarina of time something truly unique, i have nothing but love for this game
Pokemon Crystal: 251 pokemon two complete areas to explore, two entirely different Pokemon leagues, a entire subset of quests like the unown vocbulary, best legendaries and starters in memory, as a kid this game blew my freakin mind, gotta catch them all never felt like a more intense job. Aside from it being pokemon as always, i think pokemon crystal showed the best advancement in the series in years, with the exception of black & white.
What's not to love about pokemon Crystal?
Star Wars Rogue Squadron: I have yet to play a game that makes it so entertaining to shoot at things with the exception of Ace Combat 4, close call between both actually, but at the end Rogue Squadron is star wars, and flying that x-wing through the death star ravine, is something that any star wars fan should experience,
Shadow of the Colossus: I don't think there is much i can say, that the other members havn't said about this game, for me one of the first examples of how could video games strive to become something more than just simple entertainment. still eagerly awaiting the next masterpiece, the last guardian can't come sooner.
Batman Arkham City: No love for recent games on the majority of the lists, so i tried including some on mine, I'm a huge bathead, so i guess i'm biased as to how much did i love AC, however it was not just that for a second time rocksteady pulled off the "it's not just a great superhero game, it's a great videogame period" but how the game fleshed out, one of my main concerns or grudges against current gen games, is that sometimes
they try to be to gritty or convoluted with stories that sometimes they drag on forever. Batman Arkham City had just enough to never feel old and always mantain you on the edge. It's not longer than it needs to be and the whole experience just really sets a cherry on top of the pie with that ballsy ending.
My biggest surprise wasn't the ending though it was just how much more enjoyable it feels to use the side characters than batman. It's the bats we get it an he feels like batman ought to feel, but catwoman, robin, nightwing steal the show, i just wish i could use them all while free roaming the city.
Baldur's Gate: all those things i said about FFVI, but now about baldurs gate.... such a perfect game....
Red Dead Redemption: While it suffers from some issues, RDR is a game that broke a barrier in storytelling, proving it doesn't need to be evil empires, or space marines, John Marston is one of the greatest characters in gaming (for me at least). From how the world is set up, to the immense cast of memorable character RDR is one amazing game.
Bastion: In between batman, dark souls and many other games bastion managed to over shine most of the bigger competition, Maybe not everyone is a huge fan of the narrator, but between building your own custom difficulty, the story, the color, everything i couldn't help but fall in love with this game.
So there you go, that's my list which by the time i'm done a bunch of other games that didn't make my cut that should like Assassins Creed, Dark Souls, Mass Effect, Rayman, Mario, Contra, Street Fighter, Gran Turismo... see? this is why i suck at making lists =P
