A game I have never played before is Magic the Gathering, I've known loads of people who have played it, and some who were very into it, but it never really crossed my path before now, or at least I was never asked to play a game.
It may sound sad but I was very into playing Pokemon when I was younger I was in a league and played in tournaments, although I wasn't that good at it to be honest and I preferred Pokemon cards for the collecting aspect plus the artistic value of the cards as some of them looked great.
I must say even though I was sure if I would, I really enjoyed magic and I'm looking forward to building myself a strong Red deck to play a few games with friends.
