I must be in the minority because I don't like the idea of downgrading.
I think actions in games must have consequences without having a way out. I like Elements because you really have to think what card your should upgrade. If you could just downgrade it and upgrade something else, the whole process of finding the most important card to upgrade would be meaningless.
This is similar to a "buy back" option that many games have (which I also hate). It's all too easy mode for me. You upgraded a wrong card? Too bad. Maybe your learned something.
I don't see anyone suggesting that you should get the entire 1500 electrum back when downgrading, so there's already the consequence of losing electrum. And since we can already sell cards, why shouldn't we be able to sell upgrades?
If you think downgrading would make the game too easy, then you wouldn't have to use it. (Nor would you necessarily have to compete against those of us who do. There could be two high-score lists, one of which only players with no downgraded cards could submit scores to, and an option to prevent players with downgraded cards from PvPing players with no downgraded cards.)
Actually, the sell price is 75% of the buy price, rounded down. (I remember SG said that somewhere)
Do you remember what the current version was when SG said that? I think the system must have been changed later, as almost none of the prices I've recorded agree with this...
I remember talking about this but I have no idea what I said earlier, and whether the price has changed or not since.
What I do know is that right now the selling price of a card is about 68% of the buying price, give or take 1%.
Yes, this is more like it. The selling price minus 68% of the buying price varies from -1.28 for Immolation to 2.56 for Golden Dragon, and is zero for cards with buy price 25 and sell price 17.
I'd still like to know if there are any non-rare cards for which the buy price minus the sell price is not 2, 8, 18 or 32. (Since my earlier post, I found out that the difference is 2 not only for pillars, but also for skeletons -- buy 7, sell 5.)
i agree with that too, that it should use electrum to downgrade
PuppyChow isn't saying it should cost electrum to downgrade. He's basically saying that a player should be able to sell an upped rare and immediately buy the unupped version -- except that since no buy price is listed for rares, he's assuming the buy price would be equal to the sell price.
