Games I own multiple copies or versions of
...because I'm terrible with money and sometimes things are on sale on the PC, so why not? Also a lot of HD versions up in here. And some of these might be slight remakes or upgrades of each other, but I still grouped them together (see: Persona 4, Half-Minute Hero).
I'm not going to count a PS3/PS4 version and Vita version as two separate copies of a game if I got them at the same time with Cross-Buy. And this list is definitely not 100% complete, but I did my best.
