Somewhat. Unlike the true collectors (who will buy anything so long as it's cheap), everything I buy is something I really want to play. At my current pace it'll take me years to get through it all, but I intend to play everything in my "collection."
I picked up a copy of Final Fantasy 3 for the DS, Final Fantasy Chronicals, Gran Turismo 2, Resident Evil 2 for the PSX and Super Smash Brothers for the N64. Hopefully soon I'll get me a copy of Parasite Eve 2 as well.
