The games I continue to play are Half-Life (mods and level packs) and StarCraft.
Like most of us, I don't have a lot of time to play games, and there are MANY games I want to play, so I don't tend to play games more than once. I'm also not a big on-line gamer, so I place most of a game's value in its single player mode. The games I have the fondest memories of playing are System Shock 2, Half Life, Thief, and StarCraft. I also have to admit that the Resident Evil series is a guilty pleasure, but I've only played them on a PC.
Give me a deep, coherent, memorable story with great gameplay and mechanics over good multiplayer anyday
