Most of my consoles remain disconnected when I'm not using them, so no, that wouldn't interest me very much. I HATE paying for games over and over. It's just stupid. If I bought it once in 1989, then I don't see a need to purchase it again in 2012. I've purchased ALTTP 3 times now. Once for the SNES, for the GBA, and then on the VC. I don't know why I even purchased it for the Wii other than the excitement of playing it on a new console (which faded REALLY quickly). Paying for it again as DLC make the least sense to me since, when purchasing a game, you're actually only purchasing a license. If I purchased that license in the 90's, then why do I have to purchase it again just to play it on another console?
I can take a book to another room, city, or state and read it. Hell, I can even scan it and read it on my computer if I were so inclined (and crazy). I feel that I should be able to (legally) use my license for a game that I already purchased on another system.
I know what you're gonna say, "DLC games often add features and whatnot which could easily be marketed as a new or at least revised/updated game, thus warranting re-purchase". My only issue is that VC games offer NOTHING new over the original experience. ALTTP is exactly the same thing on the VC as it was on the SNES, unlike the GBA version which has actually been worked over a great deal in order to fit the format PLUS the new features. I don't feel bad about my GBA purchase, but I am sorta peeved that I paid for Zelda on the Wii again for no good reason.
