My Dad always says that collecting physical CD albums is pointless now that everything is online. He has a big CD collection but of course our times are very different. I aboslutely love having physical copies of something over digital. It's in your hands! You OWN it, and you can display, look at it, do whatever! It's yours forever!
I love my book shelves, with a big variety of books! I've got Manga, Magazines, Comic Books, Family Guy Trivia Book, Computer Manuals, just a bunch of random stuff.
Obviously I collect Anime Figures. I mean, anime characters are so cute...and then in a 3D form, even cuter, and then in real life sculpted awesomely! If you'd like to know more about my collection, check me out on MFC here! (Feel free to add me as friend too!)
As much as I love physical copies of things, I also enjoy the archiving/preservation of digital media. This includes old games, websites and overall obscure and lost internet culture. I have many folders with many files of just abandonedware, images from archived websites and more. Here is as well a list of interesting and cool websites I've found over the years:
I'll be updating the list every now and then.
