I wish that I could get into Funko Pop! for the sake of Dishonored 2.
They have made some pretty amazing Corvo, Emily and Outsider versions from the upcoming game, but I could never get into it, even for my favorite gaming IP.
I usually collect Delorean model cars and BTTF-related stuff, but I've gotten more into collecting Dishonored stuff.
There's a replica bonecharm that I bought recently (should be arriving any day now).
I also have a tarot card deck from when I pre-ordered the first game.
The 2nd game's Collector's Edition comes with the steel case, Corvo's mask, Emily's ring and an Empress Delilah poster, so I'll post the pics of that stuff when it comes on on November 11th.
Video game consoles and games from the first (Magnavox Odyssey, 1972) up to the Sega Dreamcast (1999). And I own the vast majority of the ones in between. Also X-Files stuff and, more oddly, VHS tapes of cartoons that I grew up with as a kid. I pick them up at Goodwill any time I see them.
I see a lot of people going after the Pop! dolls, and I have a few, but to me it's tough to collect for something that literally just sits on a shelf. I think that's why collecting video games is so attractive to me.
