Louis L'Amour books/original pulps. Think I have most of the books. Long way to go on the pulps.
Star Trek novels / Robert E. Howard (creator of Conan and Kull) novels - just like to read them. Quick, fun escapes from reality. And I don't mind re-reading a good one.
Sierra On-Line titles - I have a nearly-complete PC run from 1984-1996. Missing about a dozen titles, counting re-releases, and Quest collections (and minus the "award winner" collections). Considering expanding the collection to include the other systems and go after the On-Line Systems titles. Just afraid that it'll lead to having to have the hardware to run them.............
DVDs - I have about 1200, and about 50 seasons of TV, 28 of which are Star Trek (I have all of the series, including the Animated Series). I probably need to trade/sell about 100 or so of the movies. Working on condensing them down to .28mm cases (half-width) with custom covers to save on shelf space while keeping the visual appeal.
Video Games and Consoles - I like having all the US consoles (except for the Neo-Geo), and I purchase the games that look interesting to me. Even though I rarely have time to play them for more than a 30 minutes a few times a week. If I'm lucky.
Comic Books - I have nearly a 30-year run of X-Men titles, among dozens of other titles and misc issues. I really need to pare this collection down to the essentials. I'm at 35 long-boxes now, each of which holds about 300-500 books, depending upon if I've bagged and boarded them for storage or not. Yeah... overkill. Hard to believe that it all started with about 3 dozen that a tenant left in the trailer that my parents used to rent out when I was 4
Live music shows (digital collection) - Mainly artists I like (Eagles, Genesis/Phil Collins, Zeppelin, Aerosmith, Richard Marx, Sarah McLaughlin, some Johnny Cash, some BB King, Kenny Wayne Shepard, The Police/Sting, Journey, Bad Company/Paul Rodgers, Queen, etc). I dont have to have every show out there, but I like good-quality soundboards and audience recordings. Some live shows, so long as they're professionally shot so that I dont get annoyed at the jittery handycam vids. Not afraid to junk out large portions of concerts I've downloaded and only keep the songs that I want...these are for enjoyment, not for hoarding. That's what the rest of my collecting is for.
God, I need a large house and an understanding wife..............
