As a seller, you may have up to 5 listings on the Bazaar at a time and once a starting price and closing time have been set you will be unable to prematurely remove the listing. Other players will then be able to bid on your listings and once the bidding window is up the winner will receive your item and you will receive the gold they bid on it.
I love trading in Wow, 2007scape, (even diablo3 at the time)… but man, 5 listings is like barely trading. I’d argue for runescape-style, where you can have a set number of listings per item category (mostly to stop players from buying out all of 1 item and then artificially setting the price). Like 5 weapons, 5 armor, 5 mat of X…
Bidding is a really boring mechanic in my opinion, and also can lead to items selling for near nothing. I think 2007scape GE with the option to buy-instantly, or even if no one is selling, put a buy price, and other players can sell at a lower price, but then instantly sell to high price and make more money is a lot better.
I know grinding for items is fun, but due to variance, you could grind for (hyperbole) a year and not find the item you want, but have millions, billions of gold to buy said item… if only you could sell the other good items (but not for your class) to other players.
Anyway, regardless, it’ll be awesome fun to trade with other players, but as someone who loves trading (and playing), I don’t know if I’ll even bother with the Bazar if it’s bid-only and has a max of 5 items.
