Entertainment section
There is already a section "Off-Topic" for discussing games and other stuffs that are not related to cryptocurrency. Moreover this is a crypto forum. We come here only for learning and discussing crypto related stuffs. There are a lot more forums out there for other purposes. This is not a generalized discussion forum to have a board for each and every thing we encounter in our life. Gaining activity for no reasons seems to be common here. If such a board is created it would get trashed similar to the Off Topic Board. This won't cause the reduction of spam rather it would increase on a larger scale.
Gambling Section
Have you even checked out all the boards of this forum? If you had checked, you would have seen a dedicated Gambling Board for Gambling Discussion to take place. Good profit? The forum already has lots of reserves which will keep the forum running without losses for long time. Forum ads, 10Btc and 50Btc Donations which were made long back is still helping the forum as said by theymos.
VIP section
There is a separate board for Donators to discuss which cannot be accessed or seen by normal users like us unless we donate 10Btc to the forum.
Local Boards
There are already a lot of ton of local boards. Aren't you one among the boards? If you need a separate board, you can always request for it here in Meta.
All of this are not really that necessary but if other members will agree with this then I will appreciate it.
All the boards you requested are already present here. If you have already gone through the forum you would have not created this topic.
Bitcontalk.org forum is far more better and thus I would like for bitcointalk.org to continue on the improvement. As a member of the forum I would like to see some improvements or even monopolize other forums as well.
Patiently wait for the new forum software till 2020-2021. That would be one of the most expensive discussion forum ever developed with a budget of 6900-10000 Btc (Though I am not pretty sure) and almost 6+ years in development. I assume the final product would be jaw-dropping when it goes live. If you had been actively watching the development, you would have seen the beta version which was live for a couple of months.
