Role Playing Games
I've been playing tabletop and computer RPG's since around the age of seven or so. My offline favorites are Dungeons and Dragons and GURPS (Generic Universal Roleplaying System--one rule set, any setting!) My electronic favorites are Baldur's Gate I and II, Neverwinter Nights 2 , Oblivion and Skyrim, Mass Effect 1/2/3 (despite the ending!), and to a lesser extent Dragon Age: Origins. My tastes tend to run to Tolkienesqe, semi-optimistic "Heroic Fantasy" as opposed to the relentlessly dark, grim, gritty or "realistic medieval" fantasy that's been popular lately. (Hey, it's FANTASY--it's supposed to be idealistic!)
I also enjoy creating rule sets for tabletop roleplaying games. You can see some of them in one of my early development class assignmentshere and a full site dedicated to one of them here.
I also built a web site for my local DND gaming group: SemiDND.com. You can look around the site by using the user name "Guest" and password "guestTemp".
PC Games
It's not all RPG's with me. I also enjoy some more action-based games as well, though they generally have to include some sort of sci-fi or fantasy elements to catch my interest (I see the real world every day on the news, and the sorts of modern military shooters that are popular now make me weep for the state of humanity. I have no issue with getting enjoyment from the virtual slaughter of tons of demons, or robots, or zombies, or whatever--but murdering tons of "real-world" human soldiers, who had friends and families and children and everything, is not something that I think should be "fun".)
And, of course, the more world-building and story there is, the better--so I gravitate toward games like Deus Ex (the first, and the much more recent "human revolution", both of which are FANTASTIC games.) Crysis is great once it shifts away from the aforementioned slaughter of human beings and focuses more on trying to repel invading aliens.
On rare occasions I'll also find a strategy game that hooks me--Heroes of Might and Magic did, as did Warcraft and Starcraft. I used to be a fan of space flight and ground-mech simulators like Wing Commander, Freespace, and MechWarrior, but no one makes them anymore... at least, not in single-player form. It's all competitive PvP now, and I'm not very interested in that. For one, I like my escapism with a heaping does of heroics, and getting fragged about as often as I frag someone else isn't very heroic. For another, PvP matches are inherently static, or at least circular--you never really move forward like you do in a single-player, story-based campaign. I guess I'm driven more by a sense of progress than challenge.
Electric Vehicles
I'm big enthusiast of electric mobility (although there's no way I can afford a Tesla!). I have two electrically-driven bicycles (three if you include my wife's) and will, at the earliest opportunity, get an electric car--probably either a Nissan Leaf or--in 2016 or so--a Tesla Model E. I'm constantly outraged by how expensive most automakers debut their EV's at--there's no good reason why a 75-mile EV should cost $40,000, especially for a large automaker that has the resources to sell something at-cost in order to corner the market the way Toyota did with the Prius.
I have a 2006 Pontiac Solstice that I would love to convert to an EV, if I should ever be able to afford doing so. (The car's been in an accident and had restorative bodywork, so it's probably no good as a collector's item anyway--despite the fact that they were only built for a few years, and mine's one of the first-year models.)
