That's not spice; it's the opposite: making the game even easier. Far too easy.
Spice is adding variety or more of a challenge. That's why so many of us vets are doing the No-Bazaar challenge right now.
Furthermore, a -direct- advantage simply because of how long you've played isn't entirely fair, nor does it seem to be the developer's goal. Electrum is not the way to go for this.
Other suggestions like being able to buy a Nymph for a million are more in keeping with maintaining game balance. Yes, Nymphs can be strong, but not that strong. More HP, mark increase, draw power, number of copies.. messing with any part of the game's mechanics changes everything.
