1) Are you fearful of the HuCard dying on you?
2) Do any of you have this game (or your collections) separately insured? Some of the larger collections out there I'm sure an insurance company would be hard press to paid out a claim for if there ever was a theft/fire/flood.
Finally... and this is a little bit off topic, lets call this question 2a) Do any of you have your pinball/arcade games separately insured or at least on a separate surge protected circuit breaker? Those of you with rows of actual arcade machines.
I'd like to point out that CPS3 hardware suicides and a up to a few years ago a working CPS3 w/ 3S were going for $500 whereas dead(suicide) setups could not be given away. After a decade, Darksoft figured out a way to zombie carts using a glitch in 2nd Impact. Now only the "collectors" pay top dollar for original CPS3 stuffs and the players get 3S for under $100. In other words, the community fixed what was thought to be broke.
Even if MC cards die or get f*cked up, we do not know what the future may hold for basement engineers and tinkerers. Hell, 3D printers are a FACT and electronics get smaller.
I do not insure my cabs(nor anything for that matter) and only use power strips on them. Half the fun is repairing them anyhow!
If I had a MC I'd keep it. I like the game.
