Yeah, I've often wondered if I'll regret spending my Steem on cards instead of Hive... but I find it pretty fun so I figure it's probably worth the price of admission. I'm not super sure how easy it will be to sell all my cards if I ever decide I don't want to play anymore... but the team seems pretty proactive in finding new markets so hopefully it's not really an issue.
That was the basis that we were going off... if the food and the containers got nuked and steaming we were probably good... but it definitely felt weird microwaving food that was already pretty hot, still, it's a new world out there.
LoL XD
Theoretically the cards that aren't being produced anymore should be more valuable down the line but I don't know or care how these things work, I just play with the cards >_>
Theoretically yes, as long as people still want those cards.. but if no one wants to play the game or collect the cards... or newer cards are more interesting, fun or powerful then that may not apply.
When I am playing I'm usually on the lookout for older cards to upgrade mine and statistically I'm unlikely to be the only one (or the only completionist ;D)
