At the risk of being flamed, I will also throw another idea out there. (And again, this is a thought exercise, it's not fully formed but might make for an interesting discussion).
Make everything stocked, all the time, in unlimited amounts. But, make "rare" collectibles super expensive.
So for example, make the yellow letter like 5,000 TBT. It just occurred to me as I type this that that might kill the marketplace. Hmm...
But, we can still have trading because things like eggs and candies are available only a limited amount of days out of the entire year. And of course, feathers.
Just throwing it out there. For discussion.
I was thinking of this too a while back, the shop should sell the rare collectibles for like 1K, 5K, 10K, 15K+ and prohibit the exchanging of ACNL bells for forum bells
that would keep it rare but at least still obtainable
and it would encourage people to post more on the forums rather than just trading ACNL bells.
200% YES to both. That would bring upon a major overhaul to the current trading 'environment'.
(the bells conversion could still be arranged privately though, just like any other trades, I suppose)
