I love gaming because you don't need other people on hand to play. There's also such a variety between all the genres. I don't need a friend with me if I want to play Uncharted 2: Among Thieves, but I would if I wanted to play a sport (or even the cinema, it's weird to go by oneself). I also love it because it can be an individual or group event (online, SP campaign, co-op etc).
