Yep. Mostly handheld ones, although almost all of my Playstation games have disappeared, thanks to moving and storage and a pain in the ass brother...
I just then realised I don't know what happened to my copy of Pokemon Ruby, which makes me sad. I still have Emerald and Sapphire at least, but Ruby was the first one I got, and now I don't have the whole generation. Actually, I have two copies of Sapphire, and I have no idea how.
I have over the course of my life owned all Pokemon games up to generation three. Now all I have is Sapphire, Emerald, Fire Red, Blue and Silver. Where the fuck are they going!?
