I do.
I have the Famicom and Super Famicom versions of Final Fantasy.
I also have Gameboy Advance, PSP, VITA and PS3 Final Fantasy Games. My PS3 died ages ago and I refused to purchase another one out of principle. I had already bought the console for like $500, I wasn't going to double dip. Once the PS3 is $100, I'll get one so I can play some of my old games.
The reason I have a lot of games for consoles I don't own is that I collect FF games, I try to also have the majority of my collection sealed (when possible and affordable) so whether or not I can play the game is irrelevant. I've played most FF games already, playing a different version of the same game on a different console doesn't really matter to me all that much.
