I've got a couple questions about v6...since there will be custom biomes will there still be the new flowers in it and since they took out roses whats gonna happen to spawn since foob used roses in it? Second will we still have a market or will all the shopping be done on the site? Lastly since there's custom biomes how will we get podzal and packed ice?
Not originally, we'll be adding them on land revert so that when the land is reverted back for whatever reason (Decided to remove chunk, player has been banned or inactivity of sort) the land will include the new flowers etc. on re-gen.
Reverting meaning the land returns to how it was before a player altered with it, which will be its most natural state. These natural states are saved during 1.6.3 and will not include any data from 1.7 in order to add data our code will change some of the flowers and add other new natural blocks/items to the zone in order to keep it up to date.
Player shops will still be viable for all players, yet not the preferred option and will not be very effective as the global auction is in place. Most players probably won't want to not use the auction, its highly convenient and well designed. Price changes, graphs, advice and just tons of information about trades that'll make it easier, reduce price scamming, noob-friendly
and fun.
Podzal and Packed Ice will be updated like the other biomes, on revert. The Mining or also know as (Resource) world will be a fantastic way to pick up the new blocks without even reverting land. The Mining world resets per month which means the content will always be fresh for harvest.
I hope that answers all of your questions, if not feel free to post below.
