Meh, give it another 10yrs and Wii games will be selling at the original prices. Rip game/vintage computer collecting. You were a fun and inexpensive hobby until the rich assholes got to it.
There are still companies that make physical copies, but typically it's in limited quantities and sadly I've found that most of them (especially one of the big ones, LRG) can be pretty scummy. I think the only two I've found that are worth buying stuff from are iam8bit and fangamer.
I know you're joking, but if you actually have a bunch, you might want to take a look to see what version you have. There's a very specific version that gets used in the speed running community so it might be of value to someone.
They just released Riviera: The Promised Land on Steam for $35, so I don't think retro games will maintain their value. Studios will just re-release them and charge full price again if the secondary market heats up.
True, but a card or a comic isn't dependent on an equally old electronic device to be useful. New in box retro games have value as collector pieces, but used games that have modern re-releases are much less valuable.
