Been playing tabletop RPGs for nearly half my life.
Savage Worlds is my favorite system, I also played Call of Cthulhu, DnD 3.5, 4e, Vampire: The Masquarade, Mage, Gumshoe, Fallout PnP, Warhammer, and a few smaller ones that escape me at the moment. I mostly GM but I do like playing.
Right now involved as GM in a FoE and Fallout campaigns, and playing in a superhero Savage Worlds campaign. The last one is especially fun since I'm playing an average Joe pretending to be a superhero, and the rest of the party has no clue so far.
I used to play MtG but dropped it because I just couldn't get into it seriously.
There's a fantasy/tabletop club in my town with meetings each week so there's always someone to play with. Settlers of Catan and Bang! must be two of my favorites from the club's stash.
I'm currently debating the purchase of XCOM Board Game, too. If anyone has anything to say about it, I'd be glad to hear it!
I love tabletop, unfortunately I live away from any big city and don't know how to drive, so I can't play.

I second Silver Lining's recommendation of Roll20 and Cockatrice. The only reasons I'm not playing on Roll20 are timezone problems, and my irregular schedule. But I've seen how it works and it's the second best thing to being there in person, especially if everyone has mics and webcams.
There are online versions of many popular board games too, I know for sure there's online CAH called "Pretend You're XYZZY" or something like that, and I swear I've online Settler of Catan somewhere...
