Yeah, especially some of the games that were meant to be played "live" on specific days.
However, the worst part is that even if you track down a cart with one of the games you want, some of them had
expiration dates.
Back when I was in Japan, I bought a Satellaview cart on Yahoo Auctions that had "Panel De Pon '98" (an exclusive Tetris Attack variant) on it.
I booted the cart on my Satellaview, clicked on "Panel de Pon '98", and got a message saying "this content has expired" and the game got erased.
Also, there were a bunch of games released for Super Famicom & Game Boy via "
Nintendo Power" cart machines in Japan that could only be obtained from in-store kiosks.
The in-store kiosks are long gone so the only way to find a majority of the games is to track down a cart that still has the data saved on it. (a handful of games were re-released as retail games but many are extremely hard-to-find/expensive)
The whole issue of games being "lost" is my biggest fear of games going digital-only.
As companies go out of business and/or lose licenses, games get pulled from digital distribution channels and are effectively lost forever unless you can track down a
console that still has them installed.
This has already happened with a few games I was interested in:
-WiiWare - The Magic Obelisk
-PS3/360 - TMNT: Turtles in Time (remake)
-360 - TMNT: The Arcade Game
-360 - OutRun Online Arcade (also PS3 outside the US, I believe)
I was lucky enough to find out about the TMNT games and OutRun being delisted shortly before they got pulled so I grabbed them but I'll probably never get to play The Magic Obelisk.
