I'm a long time gamer, playing on and off since my years in high school back in the late 80s. I'm always (time permitting) up for a game; my main genres of interest tends to range from fantasy (high or low) to science fiction, cyberpunk, and post-apocalyptic. I tend to like harder edged systems (sans rules nazis, of course), although if the story is good and the GM better, then there's nothing wrong with a good story based system. Humor oriented games are fun too, although they are best served in moderate amounts; my take is that the best gags and jokes come out as we play (unless this is something like Paranoia).
One thing I would love to do is get an opportunity to play some of the classic modules of 1st Edition [A]D&D as I never had that opportunity. Most of the games my group of my early years were most decidedly not TSR products, so I always feel like there's something missing in comparison to my peers' background(s).
I'm also a long time reader of "classic" fantasy and science fiction. I cut my teeth on my father's collection of paperbacks and thus became well versed at an early age in the likes of Norton, de Camp, Moorcock, Lovecraft, Anthony, Asimov, Tolkien, Zelazny, Howard, Lee, Leiber, and many, many more. I like newer authors too, but these will always hold a special place in my heart. Again, given the time, I'm always up for a good book, doubly so if it's from the golden/silver age of the above genres.
My ideal game (as of late) idea is a hodge-podge mix between the hard edge science of Morrow Project/Twilight 2000, the ruin of post-apocalypse Gamma World/Aftermath/Mutant Epoch, the doom of untold epochs courtesy of Lovecraft, Derleth, Bloch and co, and the high fantasy (and epic glory in comparison to its death rate) of Dungeon Crawl Classics. Mix, bake and serve piping hot, like a hidden gem first discovered in the back pages of a 1930s issue of Weird Tales.
