Some of my personal favorites would be Silent Hill 1, 2, 3 ( 4 was ok, but I don't really consider it a SH game), Fatal Frame, Final Fantasy 7, most of the Smackdown! games and Diablo (PC and PS1). I also tend to like games where I can do Co-op modes with a friend of mine ( LoTR: the 3rd age and Batlle Hunter come to mind). I used to play Everquest and WoW, but stopped due to boredom from the same content over and over. I also like RPG's, but nothing that has a futuristic feel to it.
I actually have a working Atari and Coleco as well so I can play some of the older games if I want. Asteroids, Q-bert, The Smurfs, Missile Command, Zaxxon and Pacman have to rate among my favorites for the old systems.
As for the Nes/Snes which I also have in working status: Bionic Commando, Super Smash Tv(Snes), Mario Rpg(Snes), Mega Man 2, Gauntlet, Maniac Mansion, The Goonies 2, and all of the Teenage Mutant Ninja Turtles games work for me.
As for the old school Paper and pencil, tabletop D&D, I love playing that even today. Unfortunately, the guy who used to DM sort of stopped after his brothers moved. I would really like to try and find a way to play online, but generally it is tough getting people to show up at the right times to play.
