If it's useless, I have it.

More specifically, I have a large collection of old gaming magazines. Some are Nintendo Powers I inherited from my cousin. I became a fan of T&T when I found an article on FF7 which led me to pick up a copy of the game (I didn't even remember what FF was until I actually had the game though). GI, OPSM, PSM, Edge Magazine.

I also have a small collection of items that could be used as blunt weapons: pool cues, mop handles, baseball bats, planks (those which can be wielded single-handed)... originally, I collected these items because I like to fiddle with them and twirl them around like I've seen in those karate movies. You might suppose I could just as easily have used a baton. However, I just don't consider the baton to actually exist in this reality. I can't use it and I can't imagine why anyone would want to touch it. I mean, throwing a stick around sounds useful if you want to hit someone or have a dog to play fetch with.

I still have my original Nintendo games despite not having a working system.

My mom collects cat figures. I know a girl who collects old-fashioned keys and items designed to look like them (including pictures of them)
