Mass Effect and Tales of Vesperia. :D Hands down, the best games. Evar.

Pretty much all the classic mario games. No question.

^ This

My favorite games are:
Tom Clancy's Rainbow Six Vegas 2, mostly for the gameplay. I like the character customization and the fact that if you choose a heavy armor set, you can withstand more damage (unlike CoD or other military like games where you can easily get shot and die or whatever...)

Red Dead Redemption. My fondest childhood memories was me playing make believe with my friends as cowboys or knights (if a medieval game came out like RDR, I'd so get that). The graphics are superb and the story is good and the multiplayer is fun with a bunch of friends who like to have a good time and don't take crap from other players who try to mess with your posse.

Brink,(it hasn't been released yet) but from what I've seen in trailers and reviews read, I am very anxious for this game to come out.

And I like other games, but they're not like my favorite. But those are my top three favorites (no specific order)

yay for the kingdom hearts (actually i was in the progress of making a D&D 3.5 class called keyblade master, it's still in the works, and yes only the two on the PS2, I'll let BBS slide, but all the others can burn), I also love Fallout 3 (and vegas, although it can be a pain at times), I love the works done by Level 5 (notably their PS2 titles Dark Cloud 1&2, less the second dark cloud, and rouge galaxy), the .hack series, I also loved the Perfect Dark 64, and CoD, there are a bunch more and I would love to get into some newer game titles, but I have no next gen system and my PC bites hard and can not play newer games at all.

so yeah that's a yes I love video games, a lot :3

I got frustrated with New Vegas. It was just too darn long and Hardcore wasn't as Hardcore as I expected. I mean, I practically punched my way through the wasteland, no kidding! Unarmed ftw!

I saw how easy vegas was on regular mode when SSoHPKC was doing a let's play on it, he had so many caps in so little time and was practically rolling in food and water, he had to spend most of his videos going back every few minutes selling stuff.

System Shock 2, Deus Ex... two of the best games ever made came out at the same time :)

*bows his head respectfully, daaaaa'um gooood titles*

There are others, naturally, but those two stand out the most, even after all this time ^.^

Super Smash Bros. Brawl: In my opinion one of the only reasons to buy a Wii. Yes, there are things I dislike about it, but given the right group of friends this game can provide literally endless amounts of entertainment.

Metroid Prime 3 Corruption: amazing soundtrack, great graphics, epic boss battles, and to top it all off, the wiimote controls are perfect.

Left 4 Dead 2 and Mass Effect 2: Do I even need to explain? Lol

Dance Central: Its just...its just too much fun xD

The MegaMan Battle Network series. Despite being limited by the fact that they were GameBoy Advance games, I really liked the combat system. Clean, efficient, and a lot of fun.

Crysis is a bunch of fun, because it lets me skulk around, snipe the entire military population in a given area, steal their shotguns, destroy an adjacent area, and then run the next bunch of people over with a truck, before jumping out and letting it blow up in someone's face.

Starcraft and Starcraft II are great fun for sci-fi nerds like me who like to drop nukes, mechs, and tanks on top of an enemy.

And Supreme Commander 2 is also quite fun, because the mech is a nuke, and nothing is more amusing and effective than sending a kamikaze nuclear device into a base, for the opponent to undo himself with.

God, I have so many favorite games... recently I've been playing Killing Floor and Doom 3 on my PC. One of the best games of all time though is undoubtedly Hitman: Blood Money.
(I just play waaaaaay too many games. )

Seems to me that all my favourites reside in the PSOne, or at least most of them:

Vib Ribbon (PSOne): Side-Scrolling Platform/Rhythm Game that utilises Audio CD music to generate the levels. It's tons of fun to have folks bring in mix CDs, grab some sodas and other things, and just play the heck out of whatever music was brought to the table.

Final Fantasy Tactics (PSOne): On the list simply because I've spent the most hours on that game. Single Class Challenges are fun, but I can't decide if the Bard or the Calculator challenge was harder. At least the Mime challenge gave you good stats on everything. Using the hacked classes for the Single Class Challenge are fun, too, like if you have a party full of Astrologists.

Genso Suikoden II (PSOne): 108 Characters to collect, an extremely fun and fast battle system with unite attacks, and, in my opinion, a wonderful story. My favourite party is: Hero, Gengen + Kabocha (for the Bow Wow Attack), and Luc + Futch + Sasuke (for the Pretty Boy Attack). Replace the Pretty Boys with Tengaar + Millie + Meg (for the Pretty Girl Attack) for less damage output, but no negatives, or Lorelei + Karen + Kasumi (for the Beauty Attack) for even less damage output, but a potential sleep to all enemies.

Street Fighter Alpha 3 (PSOne): In my opinion it's still the best 2D fighter around, though BlazBlue competes with it as my favourite fighter ever. Sakura Kasugano's my girl and Carl Clover and her sister is … Ah … What would they be?

Thousand Arms (PSOne): Really, it's not that good of a game. The story is horribly cliche and the battles themselves are ridiculously simple. But its quirky combination of roleplaying game and dating simulation (Your weapons grow stronger as you, the spirit blacksmith, infuse some of a person's spirit into your weapons, and that spirit strengthens depending on the person's affection towards you) made this a horribly fun time. Nelsha, the seamstress, is my favourite; her personality changes depending on what outfit she wears, and she fights with a sewing needle.

.HACK Series from Infection to Quarantine (PS2): The gameplay is repetitive and the story isn't the most original, but at that time I had an obsession with the anime series. Still like it even if it has many faults. I was able to save Mia (that dungeon was HELLISH to beat and required clever Drain Arc uses) but I haven't gotten all the items yet.

Tokimeki Memorial: Forever With You (SNES): … … … I swear I'm gay and I love guys. I always try to go after Rei because I think she's a boy, until the very end of the game.

I have a lot of other favourite games, but those are some.

FALLOUT FTW but I also like the 1st condemned not the second one.... that one stank for the story line.

The entire Homeworld series, Deus Ex, Half Life (original), Shadow Warrior, and Daggerfall.
