I like both evenly. When single player games are done right like Ocarina of Time, Super Metroid, Lylat Wars, Golden Eye 64, etc. You get completely immersed into the game and just want to play it till the very end. No time for food or sleep, getting to the next boss is more important than life right now.
For multi-player games it takes a little longer to find the perfect game, but when you do you slowly decay in front of your computer with no sense of time killing other players. Sometimes it can get really epic when you join a large clan and plan out strategies to take over castles or whatever and it's all you want to talk about, your family and friends just respond to you "yep, sure, great, don't care" but they have no idea how much fun your having.
I've experienced both and it's a wonderful experience that I wish could last forever.
