Even though i've never beat 1 Metroid game (I've played a bunch of them) in my whole life they're still good games and Zelda without a doubt is a good game especially Ocarina of Time,Wind Waker,and Link to the past.
Anyway, I can't say I really stick to one genre, I like just good games on their own. It does help if they're gory and violent.
Examples of which games I like:
Max Payne 1&2
Worms 1,2&3D and the variations
Severance: Blade of Darkness
Soldier of Fortune 1&2
Tony Hawk's Pro Skater series (and Underground)
Grand Theft Auto series
Duke Nukem 3D
Aliens Vs Predator 1&2
Resident Evil series
Serious Sam 1&2
That's all I can be arsed to come up with right now. Maybe I could say my favourite genre is like Action or summat.
Old skool shoot 'em ups, adventure games, platformers and FPSs are my favourites
some of my favourite games are the Metroid series, Zeldas, Blizzard entertainment games, R-type series.. an heaps more, but can't be stuffed typing them all
Yeah, MGS is cool. Zelda kicks really large amounts of ass!
I like actions games, and adventure games. And platfrom games. And... nah, screw it. I like most GOOD games, really. Like UT2004(Man, it kicks ass), Far Cry(Download the demo, now! That's an order!), Zelda-games(When you buy a Zelda game, you know you're buying a quality game), Mario Kart: Double Dash!!(Dude! It's a good game! No need to make fun of me! You bastard.),MGS2(I can't wait for Snake Eater), Jak II(A kinda "nicer" platform version of GTA), Everything or Nothing(There have been alot of lousy Bond games after Goldeneye(whic was pretty good), but here it is, finally, a pretty good Bond game!) ect ect... I could probably go on like that for a while...
And "oldies" are pretty fun too. Like Super Mario World, Jet Force Gemini, Yoshi's Island, ect...
The content above makes absolutely no sense. But I guess you've already figured that out.
I really don't go for genres any more. There's a piece of crap in every genre as well as an exceptionally good game. If I have to pick favorites, I'd say RPG and turn-based strategy. FPS and RTS games tend to be too simple (though they are many good ones, e.g. Rise of Nations, Max Payne, Mafia, Warcraft).

The best old-school console RPG is Live A Live for the SNES. It is more original and fun than Final Fantasy ever was. One of the characters (the Ninja) could sneak by real foes and fight the ghosts to level up, or slaughter the people and walk around without anyone to bother you. The Gundam strategy and action games are also really good (Encounters in Space is one of the best action games I've played, and Gather Beat 2 is one of the few strategy games I enjoy that I've beaten fairly). Streets of Rage is one cool beat 'em up (one of the few games with good sound and music on the Genesis, besides Shinobi 3, which also rocks). Deus Ex is also my favorite computer RPG. I've played it longer than any other game I own. It's so much more difficult on my slow computer than on my friend's computer. It's the only FPS-type game I'm good at.
